high hump floors were for the 4spd. the sm420 has a high shift tower on the tranny... thus needing a high hump floor for it to fit.
how i know its not stock, motor mounts have been played with, they are bolted to the frame, not riveted like factory. Truck has a 1976-79 250I6 car engine in it. it has the intake manifold thats integeral to the head. The throttle linkage was mickey moused together. And the previous owner said it is supposed to have a v8 in it, but he did not know if it was a 283 or 327
2 wheel drive perches were bolted in while 4 x 4 were rivited in
230 and 250 eng perches were located in the frt 2 frame holes while 283 perches were located in the rear 2 holes. the 292 were offset with the pass side being forward of the other side
