Ok this is what happened. I had a 1991 Caprice Wagon (305) for nearly 10 years. I had purchased everything needed to do the AC (about $350 worth). The car was totalled before these parts were installed. All AC Delco parts as they were purchased through the dealer. Parts have been sitting in a box for the past 3 years. What should I ask for these? Was told these would also fit a 350 of the same years. Will be taking pictures of all the parts & posting an ad with a fair price. I have no use for these as I bought a 96 Wagon last year & they don't fit the LT1...
