The more you cut it the better you're gonna like it, especially if you try to
put the motor and trans in at the same time. I used a 440 source pan and cut the k-frame pretty good. It has worked out well. You can see by the photo that
I cut out about 2 1/2 inches and just moved the piece with the radius forward
and re welded it. After it was back in place I trimmed the bottom to fit.
