Which 5 lug disc brake conversion for 15" wheels?

Hi everyone, I'm wanting to swap to 5 lug power disc brakes on my '68 and run discs on all corners. I've got 18" 5 lug wheels on the way and would also like the ability to use 15" rally's. Are 12" rotors the max that I can use? Anyone have a kit they've bought and would recommend? I've found that No Limit has 5 lug axles for the rear end.

For the front you can use spindles from a 73 to 87 truck and you will need to replace the ball joints and outer tie rod ends from the same year 73-87. You may have to replace the steering linkage but not 100% sure on that. With 15inch rims you can't go real big on the rotors because the caliper will run into the rim

63-70 Deluxe 5 Lug kit P/N 3081941

Anyone have luck with the 15x8 rally's from 70-87?

Are you going to lower the vehicle at all? If so you can go with a drop spindle and accomplish both at the same time. Also you can just redrill your current axle flanges for the correct bolt pattern and save some $$. Also be aware that when you run 15's and a drop spindle you can run into LCA clearance issues. I'm running 15x7 Rally's and have no issues with ECE drop spindles.

Yes, I'll be using 2" springs on the front and 3" on the rear. I don't really want to lower it much more than that at this time. I'd prefer to get an early '60s c10 to lower than this one. Those are just too cool!
