if you are doing a rear disc mod on a ford 9" here is some info: if you are running YUKON rear axles, 1995 dodge 1500 4x4 front disc brake rotors slide right over the flange.:D the wheel stud holes are bigger though. however i believe one of us posted a therad about using spacers. i used 5/8" o/d x 1/2" i/d spacers around the wheel studs. lined up the rotor perfectly.:cool2:
stock axle flanges will need exactly 1/16" ground off the flange.:(

:idea:

Thanks for the info on the rotors! :grinpimp: I've got a Ford 8.8" that I'll be leaving the stock 5X5.5 lug pattern on & those rotors will work for the 8.8"s too.

Pretty cool info. Are you using the '95 Dodge brake calipers too?

Does it matter what brake offeset you had for the drum brakes? I think I have the 2" wide shoes and that meant a different Yukon axle part number.

Or since you are welding on the caliper bracket, it doesnt really matter??

I don't think it will matter on what existing drums you have, the axle stand out ( that's the measurement from axle flange to housing flange where the drum bolts on ) on 9" & 8.8" Ford rear ends are both 2.5" regardless of the drums. With the weld on caliper brackets you should be just inside the housing flange. 8.8" full size truck housings are about 3.25" in diameter so you'll have to grind the caliper bracket to get a proper fit, I think all 9" axle tubes ( stock ) at the housing flange are 3" so you should be good to weld them right on.

Ok, I may just elimate the e-brake on my Ranger. I have a 9" that I'm thinking about swapping in place of the full-width 8.8 that's in there now. I've had nothing but problems with the 8.8 since I got it. Dumped about $500 into it with gears and a rebuild and it's leaking like a sieve from the pinion. I've replaced the pinion seal and it still leaks like crazy plus it's got drum brakes. I've only got about $140 into my 9" at the moment and can do discs for about another $100.
