thanks for the info,I'm replacing them.This car sat in a building a long time with a blowed head gasket.It is rust free and in mint condition,just needing the interior cleaned.I put a hew head and turbo on it,replaced all the vacuum lines,water pump and sensors,ect. I gave $100.00 for the car,lol. Then I bought an 86 and 87 parts cars with some decent body parts,with two complete motors with extra 87 z wheels for $150.00. I thought about selling it all,I'm an old v-8 mopar man but found out i really like the car,lol.thanks for the info
