i got another 85 ss & i want to do a frame notch. if i just cut the frame over to the factory rear wheel wells, how wide can i go? i want to run a 10"x15" wheel & i'm thinking of a 295/60 for a tire. can anyone tell me what they have done & what their wheel & tire combo is? pictures would be a big help. this isn't for traction as i just have a nice little 385 sbc, but i want the look. it's a street car too btw. thanks
