A family member bought a 68 Z28 (early 80's)that had been stolen in its past life, motor and trans where taken had a 327 with at turbo charger, turbo 400 trans replacements. It spent sometime as a show car and had the same style sunroof installed. The sunroof retracted into the headliner via a handcrank, when closed was flush the exterior roof. Very proffesional job, at distance looking across the roof it was diffucult to see the sunroof. I don't know who installed it, car was black lacquer at the time and straight no butcher job. I believe the car is back with the original owner with a 427/4sp we installed after removing the mouse motor.
PS: the 327/turbo and 400 trans was sold to a airman at Andrew Air force Base. Full body 79 Camaro was unbeatable on the street, stock 10.25 cast pistons steel crank 5200 stall converter 4:88s and alcohol ,but when it exploded nothing and I mean nothing was salvageable.
