This is a new, untrimmed 1991 Ford F250 pickup body.  Originally released for the MRC MT-10M, then re-released as the Parma #10239.  Both are long-since discontinued.  These specific ones have MRC #9332064 molded into the excess lexan on the back of these. 

These bodies are about 6-1/2" wide (7" at the outside of the fender flares) and have an approximate 11" wheelbase.

Note:  These bodies come exactly as shown:  no holes drilled, no stickers, no window masks, and no protective film over the bodies.  Perfect if you're looking to add a wrap, or if you plan on using liquid mask for your project.
