315x60x15's on my 64 Dart GT

Funny you say that.I just had a spare C-body housing shortened to 46 5/8(Flange to flange)will be 51 5/8 with the 10x2 1/2 inch brakes.I ordered new axels from Strange,I just don,t trust the C-body axels when I,m pushing 540hp!Good luck!Keep up the great work.

P.S What backspace are you going with?
