Would like to see some pictures of how some of you have kicked up the rear if your Model A frame and retained stock crossmember. I’m gonna do this on my ‘29. I’m going go up around 2” I think. I have ladder bar/coil over setup.
No pics; but I cut the rails at a 45 and then stacked the rear section on top, welded, and boxed that section. Cut the ends off the crossmember and trimmed the subframe so the body would drop over it. Trimmed the wheel well as needed.
Each project requirements will vary. Here is what I have seen posted on the HAMB, you should do more searching... Try this also, https://www.jalopyjournal.com/forum/threads/pecks-rpu-project.1134417/
