I Think I'll jump in also. I have a 72 2500 Sierra Grande a project I haven't had time to even start. It had an engine rattle after warm up (PO called it a knock) so I bought a low mile rebuilt motor (5k miles, so he says) for the truck a few months ago but never started anything or even opened the new engine hoist boxes I bought to do the engine swap. I drove this truck onto a trailer and drove it off and into my yard, and it has since sat, so I non-opted it so I don't have to pay insurance.
It has woodgrain dash, door panels, glovebox, body moulding and tailgate band. It has a headliner, cargo light, aux tank sport mirrors. It had carpet and a houndstooth seat that I got rid of. Has chrome around windows. No rare options (maybe the aux fuel tank)
