Hi Charlie, A little patience and a #11 blade with the sharp tip broke off for scribing. The void left by the frame removal is patched from the back side with thin sheet styrene. When the frame is painted and placed back on the painted pan it covers 99% of the patching and is supported. You can source suspension from a similar family of cars. I am trying to work on my posting skills and hoping to post more pictures, stay tuned for further developements........JD
