Today I was at the owners house, we found NOS rear exhaust pipes with resonators, some Correct exhaust manifolds and coil for the car. It gets better the owner thinks he finally found the original transmission, and heads. Also to throw on the pile is a NOS hood for the car. I have yet to confirm the Hood, heads, and trans. In the pictures at the link you can see the NOS exhaust pipes.
