The rust-colored 1976 is in the best shape with minimal rust. It has a 196 4-cylinder engine. I’m not sure if it runs, and the transmission is missing. It would make a great project.
The 1973 also has very little rust. I have the top for it, just not pictured. It has the long block in the engine compartment, but it will need to be rebuilt. This would also make a great project or parts vehicle—no title.
The 1977 has the most rust but is a high-option vehicle. I bought it from the original owner. It has the 345 CID engine, automatic transmission, and is an A/C truck. I was told it ran when parked, but I have not tried to start it. It also includes the original dealer order sheet and the brochure showing the owner's option selections.
I also have an LM7 5.3 and an assortment of new parts to LS swap one of them.
