I made the traditional wide-5's by combining a '36 and '37 wheel. You don't have to now, because they are in resin.
"Experience modeler" because the cab channels over the frame and interior parts need to be modified accordingly, The gas tank needs to be removed from the frame. The frame needs to be kicked up in the rear to wherever the builder wants the bed. The frame MAY have to be lengthend some, forward of the firewall, depending on what engine is used, etc. Norm always sells resin conversion kits that just drop right onto the donor parts. THIS KIT requires a car modeler of some knowledge of kit bashing and scratch building to complete.
See, I was cobbling this together for myself,,,,,,,
Norm insisted that he can market the parts,,,,,,,,,
Long story,,,,,,,,,
