79 and 80 tanks are interchangeable, and 81 and 82 tanks are. You can put a 79/80 tank on a 81/82 and vice-versa, but you would have to change the sidecovers and the seats correspondingly.

Be careful if you have an 80 Japanese model. The tank mounts are slotted. I still don't know why, but on the 80 Japanese models, there is about an inch long rod that comes out from the big front rubber tank mounts. I have no idea why they are there, but a "regular" 79/80 tank will not fit, unless you open up or "notch" the front mount. Ask me how I know this..........

Not quite correct.
The longer stubs to hold the tank mounting rubbers were introduced on the 79 models at about serial number ...4,000 (I have the exact number somewhere) Up to this number, the brackets on the tanks were "closed" and if you want to mount one of these early tanks on a later bike, you have to cut the studs on the frame.
All 80 tanks were of the "slotted" design.

I cut the tank instead of the bike, because I have an 80 tank being repainted with the correct slots on it. I just assumed it was a Japanese model thing because that's what I have. I stand corrected! Learn something new every day!

I believe I explained all this in a recent post you made concerning this. Just don't want to see incorrect info floating around. Thanks Mike for the nice photographic explanation.
