Im not much of a suspension or brake specialist, prefer working on other sections of the car. But I have no choice other than to do it myself. I have a 73 Nova project and Im looking to convert my drum brakes to disc brakes. I have a few questions:

1. Can I use a spindle from an s-10 pick-up in conjuction with forward rack and pinion steering and a nova disc conversion kit?

2. Before I got to this step in my project, I removed my front subrame, cleaned, painted it and installed poly bushings. I bought some 2x2 square tubing 3/16" thick and connected my subframes. Someone told me that I needed to align my subframe? I thought since there were 4 frame bolts, the frame would self align. Am I right?

Align, There is still play between parts, if you just snug it together you'll notice that you can still move it around, if you would have marked it first you'd been good. sorry.

There are alignment holes in the center set of holes near the firewall that go through the subframe into the body. Check the service manual, I believe they are 5/8"diameter. The factory used this method. Your car may or may not have stayed this way. You may have to play with the fender and hood alignment.

yeah like greg said you can just use the drum spindles but the upper mounting boss you will notice has a threaded hole and sticks out about an inch or so, so to bolt on caliper brackets you must grind it down about 1/2in. When I did it I used a caliper bracket and bolted it to the lower hole and then swung it up until it hit the upper mount then I could see how much needed to be ground away. Then you can just go buy some stock rotors and calipers at the parts store. I had to get the caliper brackets off ebay but Im sure you can get them somewhere. Also I had to get a master cylinder form a 74 corvette and a proportioning valve to adjust pressure to the rear drums. The stock master kept locking the front discs up.

S10s have different ball joints so the spindles will not work with nova ball joints. as far as rack and pinion, any kit for novas should work fine. But if you use a forward mounted one you will have to flip the steering arms. S10 spindles steering arms are in the rear too and they are made onto the spindle so you cant flip them.
