Be careful and make sure if you have the early or late 76 with regards to the radiator. I have a 76 vette also.

Last year I ordered an compressor, hoses, etc, mine matched the early 76 stuff.

So when I ordered a radiator I ordered one for an early 76, wrong! It didn't fit. the radiator support matches a late 76 so I had to exchange it for the late 76 model. I just got it this week and haven't installed it yet.
