hey guys
can someone tell me the difference between poly motor mounts from energy suspension? I thought these two years should be the same. NAPA is telling me these years will be the same.
1991 crew cab is still squarebody the same as 1987

1991 R3500 the part number is 3.1116R
1987 C20 part number is 3.1121R

Thanks
