Don't settle for some JV universal motor mounts you found in a magazine at the dentists office. We have designed Scout specific mounts that take all the guess and double guess work out of a GM engine swap.
Fro the Scout II, simply slide the C-channel over the frame and push them up against your factory bump stop tabs. Done. No need for jigs or even an engine test fit.
For Scout 800's, original 4 cyl. trucks will have to relocate radiator bulkhead for an LS engine to fit.
These use a GM style absorber, instead of a stiff bushing for dampening, that is matched to our transmission mount stiffness. They also provide enough clearance for our stainless steel headers.
