Easiest way to do that is to use a second frame, which will allow you to make the kicked up portion at the rear longer to compensate for the shortening effect that would otherwise have to happen.
NO NO NO. I do NOT understand why the SIMPLE GEOMETRY of this is so hard to understand.
LOOK at the 45 DEGREE cuts in the 6TH PHOTO, and how the cut ends relate to each other when reassembled. THESE CUTS ALLOW THE FRAME TO REMAIN THE SAME LENGTH.
If the cuts were made at 90 DEGREES, and the ends overlapped, there WOULD be shortening, BUT NOT AS SHOWN !!!!!
WITH 45 DEGREE cuts THERE IS NO SHORTENING. THIS IS SIMPLE HIGH SCHOOL GEOMETRY., common sense and OBSERVATION.
WHY must you CONTRADICT CORRECT INFORMATION ??
DO the mod AS SHOWN and MEASURE IT !!!!! I have done this MULTIPLE times MYSELF, on REAL chassis AND MODELS and MEASURED IT, it's accepted as correct in the history of hot-rodding and cited in MANY OLD PERIOD ARTICLES. IT WORKS AS STATED.
There is NO DAMM SHORTENING !!!!
