I just bought a drum to disc conversion. I searched every possible internet company and a few I deal with on a regular basis. The first thing they tell you is that the spindles are different. Well I put the old hub on the new spindle and it fits perfectly. I also measured th length they were the same. You could go with a two piece rotor and put it on the old hub, you would have to put on the new backing plate and the caliper brackets(no biggie). Then depending wich caliper you wanted to go with you may pay 3 or 4 hundred dollars each (minus core charge) but your going from drum so you pay. If your going to race then go with the large diameter rotors and the 2to4 piston caliper. But if not then go with a kit. So I went with a kit got every piece that I needed. All for $618.00 shipped. Suggestion get the prebent lines that they offer with the kit unless your handy at bending lines because they will break when taking everything apart. The place I got my kit from was CR custom in Ohio.(614)323-5920 or RiDE34@aol.com
Chad is the man I searched evrywhere for 2 weeks straight and he was the best.
get the master with the 1 inch bore and the 11" power booster ( rec. of Car CraftNov.05 issue) The kit fits perfectly if it doesn't you did something wrong. Hint everything is bare metal get a caliper paint and Paint it to protect it.
