After a compressor failure, I’m replacing all the main parts of my A/C system (1995 Camaro 3.4L). So, that includes the evaporator, which has a gasket (part 42 in picture below). You’re supposed to replace this gasket with a new one…mine is original and is split in one area and not in good shape. Problem is that the new part didn’t come with a gasket and the GM part number seems to be discontinued.
What should I do in this situation? I don’t want any problems down the road from not doing this job correctly.
