Redrilling For Larger Bolt Pattern

Are we talking LBP 14 inch wheels here???

I'm planning on 15's when I switch...but I thought I read somewhere that the register on the end of the axle is what centres the wheel against the flange... not the lugs!!!

I don't think the wheel centres are the same dia for both size wheels, (as for ralleys)... mags are usually hollowed out in behind and don't rely on the reg. to centre the wheel.

I'm hesitant to redill my axles...Im picking up a B body 8 3/4 rear on Monday, (wheel to wheel). I think I would rather pay to shorten the B axles instead of redrilling the A's.
