For anyone who's interested, The body mounts on my 75 are swiched out to polys. The rubber ones were definently worked. One suggestion to anyone replaceing their mounts, Go ahead and order new bolts and nuts (2 for the #1) for the whole car. 27 years has not been kind to them and now my baby is waitng in the garage for them to arrive. Dr Rebuild had the best price and there correct. (Local chevy dealer wanted $12.00 each). No suitable replacement could be found locally (within 10 miles). They're zinc coated 7/16 X3 1/2" 14 pitch with more thread then the grade 8. So, just order them. Later Wicky
