I have a crossmember for my 67 that for some reason does not fit. Is this common? I have the right one for a powerglide w/327 and the bolt holes on the tranny mount were 1/2 inch forward of the slotted holes in the middle. I ended up drilling new holes to accomodate the difference. I began to wonder if my subframe was replaced at some point with a non-camaro subframe. If anyone has seen this I'd be interested to know what they did. Thanks!
