Again, not mine, but because not a lot of Camaro guys frequent the Corvette sites, I thought I'd post it here in case you have a 1968 L6, 327, or 350 engine and are looking for a smog pump.
THIS ONE (scroll down to "pump #4) is dated October 17th, 1967 and he only wants $30 plus shipping. It's frozen, but they can be repaired fairly cheaply.
