It’s been chopped and modified.

“1956 wagon body on a 1991 Blazer frame, best of both worlds. 4.3L chevy with automatic transmission. Four wheel drive works great with automatic hubs. Strong drive train. New gauge cluster and everything works. Inside still needs finishing but functional. Body has 4″ chop and 8″ stretch to match the frame. Electric sun roof. All work was done in the 90’s so has wear and tear but still solid. This is my daily driver. Will do 75 on the interstate and go straight up a wall in 4×4 low.”
