2nd Gen. Rotor 2nd gen. calipers on 68 Camaro?

I bought a complete drum to disc brake swap off of a reputable online parts seller with the spindles in the kit lowering my car 2" on my 1968 Camaro. Well when I went to mount my new 17x8 TTII's they hit at the lower tie rod mounting point. I did my research and found this to be a common problem with this type of lowering spindle and that I should of stuck with the standard spindle and gone with lowering springs.

Well I have done that. I have my new lowering springs in place, I bought the appropriate 1st gen. spindles, dust shield and caliper bracket thinking I could re-use the rotors, bearings and calipers. Went to mount the existing rotors to my new spindles and found the bearings are different sizes on the outer bearing. It appears that when they throw these kits together they use 2nd gen. parts instead of 1st gen. parts for some reason and now I have 2nd gen. rotors and 2nd gen. calipers with 1st gen spindles and caliber brackets.

I can get the bearings figured out as I can get them custom ordered, but it appears the rotor hits the spindle at the top nut, which I am back to something rubbing again and I don't want to grind away at the top mounting nut and don't think I can find one that is smaller. I am also not sure if the 2nd gen. calipers will work with the 1st gen caliper bracket or not. They appear to line up and the geometry looks close, but until I get the bearings and mount the rotor I won't know for sure.

Does anyone have any experience with this or should I scrap my 2nd gen rotors and calipers and just go with the appropriate 1st gen. parts. I spend $450 for the complete front power disc brake upgrade kit and am now down another $100 for the spindles and $90 for the lowering springs and $48 for the dust shield and caliper bracket. The calipers and rotors would put me back about another $150 or so. I don't want to do this and want to make what I have work.

Thanks for your time and help.

The rotors won't work, wrong offset & the spacing between the bearings is longer on a second gen too. The calipers will probably work.
Get rotors for a 69 Camaro, they came with a single piston caliper, 67/68's need a rotor with smaller hub to clear the 4 piston caliper & it may be more expensive.

Thanks for the info. I guess its buyer beware, especially if you are buying drop spindle kits off of ebay. I had no idea I would end up in the situation. Now I have to replace the rotors and the calipers.

Your calipers should work. You can probably sell the rotors to a second gen Camaro or Firebird owner.
