yes, they're interchangeable, all years of II gas tanks I've seen have been identical. Since my cars seem to do a lot of sitting these days, I've been pulling tanks and sealing them with the POR Tank Sealer. ~$30 per tank. I have a '79 Ranchero that's gotten so bad that it'll clog a new fuel filter withing 10 minutes of running. I already have a freshly coated tank to put in it, but found out my sawzall (and other tools) has "disappeared" from the garage when I went to cut the trailer hitch off the frame so I can remove the tank.
