I have a late 70's full floating d60 from a f250 under my rig, and i was wondering if anybody makes a Good disk brake kit for it. Also, i hear that your have to do some machine work to put in a 35 spline axle. Do you have to do this for a full floating axle also?

TSM makes a good rear disk kit

35 spline axles won't fit through the stock spindles, you can machine them out, but I don't know the tech on that, maybe someone else will

this is what i did on my 10.25, should work on the d60 to as well as any fullfloater, tsm is crazy with there prices as are most disc brake conversions. check out my thread its cheap and easy

i pretty much did the same with my 14bolt. works like a charm. my jeep will stop alot better now than it did when i still had the big dually 14bolt drums.:D

There is a pretty good writeup with pictures here and the have the NAPA parts list. http://mopar.rockcrawler.com/brakes.htm
I used the listed rotors but made my brackets a little different. I also use the large rear GM calipers with the emergency brake.

You can ream out the ends on the housing to a bit over 1.5. Or you can use Corp. 14 ends, or one from a Sterling, anything over 1.5.

my swap is gonna end up costing about 200 total....all i got is the calipers, rotors, pads, all that stuff from the front of a 3/4 ton Chevy. then i went to a chevy dealer and ordered weld on caliper brackets for $14 bucks a piece....the rest is history!

Cool. Once all of this blasted snow stops falling, ill dust off the tools, and get to work
Thanks fellas. :D
