In that case if I had a GMC frame the 235 front mount would be short of sitting on the lower lip of the front crossmember. There is no sign of this truck using the side mounts to frame, no holes in frame. I bought the 235 rubber mount and the shield that is available and made the remainder of the mount. It sits on a plate welded and bolted to the cross member, just foward of the original mounting holes in the lip of the frame on top of the crossmember. Seams to be working nicely so far. I'm fitting the front sheet metal now so I can put me a backyard paint job on the cab. Can't wait for the first ride around the neighborhood odd ball engine or not.Larry
