Question about the 73-87 chevys?

I rode home with my friend yesterday who has a 73 year, his door panels had square holes, and he has dual tanks, I thought power windows and locks didnt come out until 77, and dual tanks until the 80's year trucks? anyone know?Question about the 73-87 chevys?
yes no power windows until 77 in the trucks



in 77 the door stampings changed under the door panel area only to accomodate power window motor mounting, and the door panels were enlarged



73-76 panels are alot smaller and the doors are stameod differently



alot of the times the 73-76 trucks have 77-up doors on them



dual tanks were around way before the 80s, ive had a million 70s trucks with dual tanks and in the 60s they were a dealer option and were installed in many different ways, the 73-80 dual tanks trucks are common, just look around you will spot them, my '77 k-10 is a dual tank truck, not uncommon at all



77 still didnt have fuel door yet, jut had the cap out in the open on the bedside

i think they offered dual tanks as an option to farmers.Question about the 73-87 chevys?
wrong. You could special order in the 70's.
according to Ackersons Standard Catalog of 4x4's 1945-2000, power windows didnt become an option till 1977. dual tanks were available as well, 16 gallon for the main, 17 for the aux.
