I think this rare, notch back, coupe version of the Monza should be left a 4 cylinder car as it is in amazing shape for any GM I've ever encountered.
Door and trunk locks lock/unlock like new, All seats except the driver's has no tearing and staining, Amazingly little rust and only a small dent or two blemish this next to 100% straight car. Only defects to be spotted is the visors do not exist and cardboard headliner is warped and too far gone to do anything about, the plastic furnishings basically dissolve if you look at it funny, no more driver's arm rest, and no carpet exists. And more than half of those is because of the "superior quality" GM products are known to have.
Speaking of "superior", a great tip for those who are willing to mess with GM H-bodies is this: expect to be using parts from any GM product of the similar time period when working on these cars, no body exactly repops many parts for this car anymore. Thanks GM!
Possibly later, I will make a new update post about this project. But for a summarization of the progress is this, the engine and trans is only a step away from being ready for fitting. Have a great Christmas Eve and Happy Holidays everyone!
