Boss 338 / Coys C5 wheel question

[BossHogg69]

I'm running a 73-87 style front end on my '69 with the Boss 338's. I have CPP '73-87 2.5" drop spindles, CPP tubular arms and 2" springs. I have 73-87 1.25" rotors and had to turn them down so the front wheel would seat on the rotor all the way. I'm running 18x8's in front with 4.5" bs, 245/40/18's. 18x12's rear with 7.5" bs, 335/30/18's and will end up running a 1/2" spacer in the rear to even out the track width since I'm running my original 69 rear which is narrower than the 71-72 rears. Look for project 'Silver Dollar' in the builds section, he's running 18's also and has a complete truck to look at, mine is only a chassis at this point.
