I wound up going with www.northwestfab.com they had one thing nobody else did: a clockable/adjustable kit. I didn't know how I was going to have to clock mine, so I went with this one (and good thing too, cause I had to try a couple of positions to get the exhaust to fit).

Second to that, I would put the one from http://www.offroaddesign.com/catalog/doubler.htm

Offroad overstock makes a decent one (pre-welded position)

Whatever you do wind up going with, I would recommend the triple sticks (twinstick'd 205) from northwest.

On a side note, a company has recently begun making triple boots now too.

I'll second NW Fab, not only is it clockable but the clocked positions are bolted in place with no welding required so it can be reconfigured for a different application.

Got a nice tip from offroaddesign where i got mine.

Use a single center mount on the np203 adapter to support the drivetrain against bouncing. The single center mount allows the usual rear double mounts to work and doesnt add stress when the whole drivetrain moves a little bit. Also good and strong motormounts are recommended. The weak point in a setup like this is the transmission, if you use an automatic with alucase. You can see this also on their website.

Personally, I've always been a glutton for punishment. I went with the 37-bajillion point lock-it-down approach... 2 points on the engine, 2 points on the tranny, 2 points on the 203, 2 points on the 205, the entire case on the PTO cover on the 205, and a lotta bushings.

If you use the same spacing for the 203 bushing as for the 205 bushings its ok. Otherwise you will create some stress points when the drivetrain rotates a little bit. ..in a perfect world
Another point is the frame flex ... which is on a m715 not really a problem


Nice setup!

Ok, i decided to go with the 440 and will probably ditch the 727 for an np 435 set-up. Here is my question if I go with the np 435 would it be worth the extra money to do a 203 205 setup like Bob is going for? What are the pros, cons? Would it be divorced or mated to the back of the trans? Is it to much gearing for any practical purpose?

I think if you run the 203 mated to the 435 it's going to be shorter. That's the route I'm taking in my J200 w/401.

I've got the modern 60 front, but it's sprung under for now. That causes some clearance problems I'll have to address at some point (read SOA front and shackle flip).

I went with the http://www.offroaddesign.com/catalog/doubler.htm I also got it clocked 2 inches up, however I decided on not getting the twin sticks. I have never found a god use for them, other than to tell your friends "Yea, she's twin sticke'd to"!

There are three distinct areas where twin-sticks come in handy:

1) When you have a locker up front and are trying to turn, the front end will tend to push/slide. By unlocking the front axle, you get better turning radius back (not like our stuff doesn't already need a 40 acre field).

2) If you have a problem with your rear driveline (lunch a shaft or cannot apply power for some reason) you can drive home in front wheel drive. This is VERY exhilerating if you have a front locker!!!

3) If you're in a tight spot you can unlock the rear, break traction on the front and slide the front end around (think 270* hair-pin).

Trails tend to be pretty tight here in the southeast, I'm more used to a shortwheelbase vehicle. I haven't wheeled my 715 yet. I used to 'wheel a CJ-7, and I could see where these tricks might come in handy with our trucks.

3. commonly referred to as the "front dig". Makes for very sharp turns w/cutting brakes.

ditto on the exhilarating drives LOL
