Three quarter ton pickups come with heavy duty coils in the back with the helper springs coming from the back as you describe.

If the SPID is still on the glove compartment door it will tell you of the original options from a base model.

Base model pickups in '71 came with non powered disc brakes.

Some guys on here can decode the stuff for you if you can post a picture of the SPID.

I am not sure, but I don't think they had electric brake controllers in '71.
