I wish you guys had mentioned this stuff last winter, when I needed to get a new one for the '78. I had to install a used one from Rod's Datsun parts, but it looked very nice and the rubber was kinda new-looking. the old one had a chip where the key went and needed welding, and the rubber was starting to dry out. It might be nice to have a spare (stock style, with two grooves for the '78 a/c) to slip on sometime, especially if it's a little lighter. Come to think of it, I might still have the old one to rebuild. Can they also lighten it a little? The bad thing is the guy that repaired the engine retired a few weeks after my car was done. :disappoin
