I have mounted bodies using a hard plastic called grilon, it comes in round bars and is found at metal supply stores, buy it in 2 1/2 inch diameter and have it cut at the shop's band saw in 1 inch slices, drill a hole in the center and use them as mounts, they will outlast your truck.
you can also use any other plastic stock except teflon wich is too soft and expensive.
I have even seen rubber donuts cut from big rig tire carcasses, they also last for ever.
don't use tranny or engine mounts, they split and let your body go.
YOU MUST USE A BOLT THAT GOES THROUGH THE MOUNT, use nylon self locking nuts and big thick washers, I'm sure they'll check for this to have it certified for the tag.
