Carl pointed out to me that the Cab Enclosure hardtop for the M-38A1 (by Metro Engineering) used plywood doors (all the time? sometimes?). Anyone have insights on this?
Here are two examples.
This video was taken in Salt Lake City (Avenues area) and shows and M-38A1 with plywood doors.
And, This thread on G503 includes the below pics of plywood doors.
