1967 pontiac gto lemans

This 1967 Le mans was my Father-in-laws car from 1971 until this summer when my Father bought it from him. It was parked in 1978 and didn't move until my father bought it. It was a 326 car and now has a 66 389 with a rebuilt 400 turbo 3 speed trans that was rebuilt before being parked. We brought it home and wen through the brakes and lines and gas tank to make it a driver.....well now for some reason #7 dose not have any compression and my dad wants to be done with it after working on it all summer.... Interior is in very good shape with factory buckets and console. Has a driver paint job that was done sometime around 76-77 before being stored. It has rust in the floors and trunk and qtrs. We just put in new intake gaskets thinking that was the issue but its probably a head gasket. She ran very nice and Very strong until this happened. It has a 68 GTO 12 bolt Posi Rear end. Factory air car and steering and brakes. 1000.00$ deposit immediately thru pay-pal and the remainder in cash or wire transfer within 3 days. We transferred the title a few weeks ago and should have it in hand in a week or 2 at most. AS IS WHERE IS
