Correct hardware for attaching the torque reaction arm.

Does anyone have a list of all of the hardware/bushings that are needed to install the torque reaction arm? The pictures in the maint manuals don't help a lot, and I didn't see anything in the parts manuals. I'm quite sure I don't have anything that I should have, or maybe not in the right place.

I would also consider buying a handful of used (correct) parts if anyone has them, then I could look for new bushings later.

Thanks everyone!

Oh, I did find a 9 year old post that might have helped, but the drawing it referenced was gone, so I'm not sure.

Where exactly on the truck do you believe this needs to be attached?

It bolts to the rear of the transmission, right side holds the exhaust bracket, left side is a bolt and a bunch of washers, spacers, and a bushing or two from what I can make out from the manuals.
Thanks!

Was it this thread?

If so this is the pic you couldn't see.

Yes, that's the one. And that picture shows up. This is the part that I think would help if I could find the 'drawing'.
"By bolt #12, please refer to the drawing below. When I got my truck, bolt #12 was missing... Well, when I finally installed the stock exhaust system this past summer, I ran a bolt up thru there to fasten the bracket. I did not put a bushing (#5), nut (#3 lower) or rubber damper (#10) in there... However, if you look at the drawing, there is a nut, #3 (lower one), and a rubber bushing (#10) that makes bolt #12 a floating stud with its base attached to the frame plate."
This post makes it sound like maybe there were originally bushings/dampers on both sides of this torque arm/transmission mount thing, and since I have it out, I'd like to try to put it back correctly. :)
That, and I have the 'engine shake' problem mentioned in the thread as well.
Thanks! I appreciate the help.

The smaller rubber insulator 1 1/2"dia. (lower right) is the correct size, the other two larger insulators are not, and I haven't replaced them yet:oops:

This bolt is 4 1/2"long x 3/8"-24. Wrong size rubber insulator.

This bolt is 3 3/4" long x 1/2"-20. I cant remember if there is a tubular steel ferrule inside of rubber as in the transfer case mounts. Wrong size top insulator.

Hmm, learn something new everyday. All 4 of the trucks I have experience with didn't have that so I had no clue what you were talking about. I guess I need to resume memorizing the manuals again.

I just remembered, there is a steel spacer on the drivers side that isn't seen in the picture. It's behind (inside) of the channel shaped arm where the bolt passed through.
It prevents the channel from squeezing together from the bolt tension.
I will try to get the camera in there tomorrow.

Barrman, this is one of those areas that the manuals that I've seen don't cover very well. Jeepdan's pictures may be the best record anywhere!

Jeepdan, Wow. Just wow. That's awesome! The pictures, and the condition of your truck, both.
That's the info I needed to get this put together correctly. Thank you!
There must have been a sale on those big bushings at one time. The only bushing I have is about that size too.
I noticed that there is something just under the locknut on the driver's side that looks like it goes to the transmission maybe? Another bracket? I don't think I have that. :(

In the interest of keeping all of this info in one place, I'd like to mention something I found last night in a post on SS from 2014. I don't think I can 'legally' cross-post so I'll paraphrase.
This is regarding the 2 bolts that attach the arm/mount to the transmission:
Replace the bolts with grade 8 studs, flat and lock washers. Use red loctite. The driver's side stud has to be shorter than the other.
The post is titled Transmission Support Mounts (to give credit to the original poster).
This is something I think I'll try since one of my bolts had fallen out and was jammed under the trans somehow, making the entire mount quite loose.
I hope I didn't break any rules by including this.

I was just about to start calling around for bushings so I opened the -34 to use the picture in there as a reference. Then I noticed that I was in the engine section. And that's when the light came on. :idea:
Yes, the torque arm/transmission mount parts breakout is in the -34P, Group 1 Engine. Figure 5.
So now with all of the information in this thread, I should be able to make or buy everything I need to make this thing work right.
As my late, great aunt used to say, 'Until you're better paid, thanks a lot!'

Yes, there is another brace, fashioned from a piece of tubing.
Photo also shows that spacer inside of the channel mentioned above.

Nice! Is the torque arm coming loose a common problem on these trucks? Your solution seems like a sure fix, and I'm wondering if I need to add something like that. Or if it's needed more for 5.87:1 and maybe not so much for 4.56:1 gears, if I make that change.
Thanks again!

This is just a list of part specs that I'm using to go shopping for the parts that I don't expect to have in the shop or find online as NOS. Maybe it will help save someone else some time looking them up.

Here it is in .txt format. Not very pretty, but it will do.

The tubular arm and the spacer are stock parts, I didn't add anything extra.

The torque arm/support bolts that thread into the back of the transmission have been know to work loose enough to leak gear oil out. It's mentioned I the Quirks Manual.

I found the spacer in the manual, had no clue about that tubular bar. I'm thinking it might be easier to make than find.
I read that Quirks manual, must have not remembered the part about the bolts coming loose. Looks like I'll be joining Barrman in the library to reread the manuals. [emoji1]
Thank you!

Get to it, mister!

Seriously, I have never seen that torque bar before. Crazy the stuff you can still learn.

Post a wanted ad.
Many members have repowered their trucks, and might have that unwanted stuff lying around taking up space.
You might get it for the price of shipping.

I've spent many hours reading through the manuals learning about every nut and bolt in our trucks.
Unfortunately with my aging mind, I can't remember half of that stuff.:confused:

The ad is a good idea. Thanks. I'll do that in a little while.

Is your truck a '69? I wonder if that's one of that year's mods.

I'm right with you on the remembery. I do what I can, the rest I write down.

The part being on a 1969 is an easy out for me. All of the trucks I have experience with are November 1967 units.

Mine was made May 1967

I was hoping! But no such luck. [emoji2]

Well, I have no option but to try to find one then. [emoji1]

Here are the hardware parts with the exception of the locknut for the 1/2in bolt that I still have to get. Sorry about the dirty rag for a background, my box-o-rags went dry. Also, I have a flat washer about mid way on the 3/8ths bolt that I think I will change to a lock washer because I think that's what is on Jeepdan's setup. And it makes more sense.
The studs are for attaching the torque arm to the transmission.
When I get the insulators/bushings we will see if everything goes together. :hammer:
Thanks everyone!

The 3/8ths bolt has to be at least 4.5 inches long. The 4 inch bolt I tried at first didn't stick up through the exhaust bracket at all. I used a 5 inch bolt and left 1/2 inch stick out above the top nut. Looks like it should be just right.

I cut the bushings out of a strip of chemical and weather resistant rubber that I found at Grainger. It wasn't as much fun as I hoped it would be. I have enough left over to share if anyone else would like to try to make some bushings, too. :) I'm not sure how long these will last. Time will tell.

The sleeve that is between the 1/2 inch bolt and the bushings I cut the length down to 1.25 inches. It seemed to be interfering with tightening the bolt at its store bought length. (1.5 inch, maybe?)
