Be sure you installed the correct washer that belongs between the bearing and the castle nut. It has a square "tip" on the inner rim of the washer that mates with a slot in the spindle. It's a pretty hefty one. If you're putting another washer between, be aware that it will be subject to spinning against the castle nut - use a good one that's not plated. The only other geometry that would allow the rotor and outer wheel bearing to go too far in would be if your wheel bearings are wrong inner diameter or height, or the spindles are machined wrong (low probability event). Might want to go buy a brand name bearing and mic it. Even better, just put that good ol' American bearing in the car! Larry's set-up sequence for torque is good, but the torque number may be too high - while spinning the rotor, take the nut to "snug" and then back off one slot in the nut. Insert cotter pin. If you have the right washer and the right tightness I don't think it hurts to see a little space between the cotter pin and the base of the castle slot. (Going from memory, but I may have seen this before.) As Larry said, check them after you put a few miles on them - you may be able to go in one more notch. I've done drum-to-disk conversions to both of my Pontiacs - it is without a doubt the best single mod I have ever done to either car. I used junkyard spindles, steering arms and caliper brackets, bought rebuilt calipers and new rotors/bearings and hoses from the auto parts store. The master cylinder and combination valve I bought from Classic Performance Parts in California - brake conversion specialists. Who'd you buy the kit from - sounds like a lame response from their tech people.
