New NAPA part Numbers - Master Swap

I picked up all my parts to do the dual master swap. The part numbers have changed from older posts so I will list them. NAPA tells me they are updating all their numbers.

NAPA Number -------- Description
G60691-0003 ---- 3/8" plug to close the now unused 3/16" port in the stock distribution block.
G60693-0303 ---- Coupling to join (2) 3/16" flared lines. (New line extension to the old rear line)
G49502-0303 ---- Adapter- 9/16" master cylinder port to 1/4" flared line
G49500-0503 ---- Adapter- 1/2" master cylinder port to 3/16" flared line
96246 ---- Dual Master (Wagner F66857)
813-5461 ---- 30" 1/4" PVF flared brake line
813-5454 ---- 30" 3/16" PVF flared brake line

Great info, thanks!!

Does that master have the two chambers the same size or a larger for the front?

The one I used was the same for both. Think others have used one with a larger front chamber.

Equal size chambers=disc/disc OR drum/drum master.

Different size chambers=disc/drum master.

In a stock truck, the first type can work while the later style wont...not well anyway...only equal types should be used with stock 4 wheel drum setups.

Forgot to mention;

$93 for everything needed to do the conversion.

Interesting.
My master (which I bought using the old part numbers last year) has the different sized outputs. But I just necked them both down to fit 3/16 line (using screw in fittings).

So this is not going to work and I need to buy a new master cylinder?

Zach, there are a number of master cylinders that will work - I used the Cardone 10-1331 and it works fine.

I should have been more specific. I have a new NAPA dual circuit master, not the stock unit

Does yours have the different sized outputs?

Zach

I don't remember - it's been 3 years since I did it - have the receipts somewhere, but I think the outlet sizes were different.

If the line connectors are a different size, no biggee...the different size fluid reservoirs are the problem.

The front brake port is 9/16" and the rear port is 1/2". This is for the Wagner master that is recommended. The stock line to the distribution block is 1/4" and I am going to keep that size so they make an adaptor from the 9/16 to the 1/4" line. The rear lines will remain 3/16" so an adaptor is required to go from 1/2" to the 3/16" line.

However, if you flare your own lines, you can get a nut for the line that fits right into the port without the adaptor. I am using pre-flared lines, so an adaptor is needed.

Correction for the master cylinder part number Napa number 36246 not 96246

Current price is $77.75 in my area. I am assuming it is new and not rebuilt.
