I`m replacing body mounts on my 74 T/A with energy suspension part # 3-4142. The rear 4 are fine but radiator support ones are much thinner by 3/4 inch, am i using the correct energy suspension part # or do i just make a 3/4" spacer. Have emailed energy suspension but no response and my supplier here in Australia hasn`t come across this before, any help would be helpful thanks.
