trimming 67 front frame rails

[kevncar]

I'm trying to get a 454 in my 67 and need to clearance the frame rails for the headers. I figure, I'll start with the factory cuts that were in the original 68s and up, and hopefully, I won't have to go any further.

Does anybody have a nice clear picture of their 68 or up front frame, maybe without the motor and everything.

I'm going to draw up a sketch so hopefully a board member can easily pull some dimensions for me so I can reproduce the cuts. I'd just like to have an idea where the original cuts are at in relation to other things so the sketch isn't confusing. (or at least not any more confusing than this email is)

Thanks!!!
