Amateur hour continues up here on the hill... We have the 5 lug disc brake conversion kit installed up front, now looking for the easiest way to do the same on the rear. Is there a later 5 lug axle that we can just grab from the junk yard and swap in? And do we need a proportioning valve with discs all around? Thanks for tolerating this old hacker. As I've always said, I know just enough to get myself in trouble... lol
No direct swap rear axle shaft by itself, you would need to convert to an open drive setup. A proportioning vale allows you to adjust the brake pressure so the rear brakes don't lock up before the fronts. Not absolutely necessary but is nice to have.
No need to go with disk brakes on the rear of an old pickup. And as they said, swap in a later rearend, from a little truck or a car.
Camaro (80) will fit but is just a little narrow. 8 in. wheels will slightly rub inner fender. also if I remember right you will need to make a new locator hole for axle pad on those trucks....I think.
On my 53 Pick Up I used a 70’s Chevelle rear end, width was just right but they are drum not disc. Go to Pic A Part with your width measurements and start looking. Of course American cars are getting scarce at self serve wrecking yards.
As has been said, no need for discs in the rear. An S10 4x4 rear will do the trick. If high horsepower, and circa 1976-ish Camaro rear will work.
