xs750 tank on kz 650 frame?

I think I am going with a different tank. In a few weeks i will make my final choice. If i go with another tank then you can have dibs on this one. It is not pefect but I think it can used. The inside is pretty rough. I am going to give it an acid wash and see how it cleans up. There is a small rust spot above on one the emblems but no big deal. The bottom where it rests on the frafe is pretty beat up. i went at it with a hammer to take care of a small cleareance problem :ohmy: . You can't see it anyway so no big deal. I will let you know. I really wasn't sure what bike this was off of. I got this bike in a load of bikes I picked up. I know it is an 82 but everyhting else on the id plate in worn away. I still have the tail piece and the front fairing. Not sure if I will use them or not. Rest of the bike is complete but pretty rough. I might steal some more stuff from it. The rest will get blasted, powder coated and put on ebay.

Heres another Photo of mine. But I have done a bit of restoration work to it and Put the frontend back together properly, Now Just need the tank, seat & battery.
Im not going to make it shine since its just a rideable bike until I get the Kaw running again.
