68 GMC Dana 44 rear disc conversion???

[Hudsonaj36]

Hi,

I have a 68 GMC 2wd with a leaf sprung Dana 44 rear end. The rear end has the big Ford ends. Does anybody make a rear disc brake conversion kit for this? Been looking around but not finding anything.

Thanks

I am interested in this as well. My drums are nearing the end of their life and new ones are unobtainable I hear.

Well hopefully we will get some info here. I’m going to call some parts places tomorrow and see if they know.

Looks like they might fit. I’ve already converted to 5x5 lug pattern.

Anybody have any input.

I have the same rear end but have never looked at discs. I did look for 5 lug conversion axles with no luck. They're not very well supported by the aftermarket. I bought everything to rebuild my drums except for the drums themselves (mine were okay) from RockAuto and it looks like they have drums too.

How did you convert to 5 lug?

I just called Dutchman axles, told them what I had And they made them for me. Wanna say they were around $350.

Finally found our drums at rock auto like 5 or 6 years ago. They went on close out and.bought last two they had for 1/2 price just to have extras. Will go to garage after my son gets home and get you part numbers. It's his truck so I dont know where he stashed them. But yes hard to find drums for gmc leaf spring setups. His is a Dana 44 with the large studs. If I remember right the first two we bought was like 50. Each plus shipping. The closeout ones were like 23.$ each. It is a centric part number I think. Will let you know.

I would like that part number too. My 2 are starting to wear thin. Disc rear would only be for me if I can't find the drums.

I talked to quick performance this morning and it sounds like the Rear disc kit will work for me. Having already switched to a 5x5 bolt pattern, finding drums that will work is nearly impossible. If I could find stock drums I would still need to have them re drilled for 5x5. For the disc kit I will have to have some machine work done to my Dutchman axles. I will have to machine down the axle flange from 6 3/4” to about 6 1/4”. I will also need to machine the center of the axle down from 3.5” to 2.77”. Then the kit should bolt up. I will update when I get the kit and let you all know if it works.
