Does anyone know about how the gas tank mounts on a 71 Alpina. Specifically the end of the tank where the side panels are joined to the tank. My tank has some stress fractures in that area causing it to leak. Before I remount the tank I need to know exactly how it should mount. On my bike and what i suspect is the cause of the stress... the air box was not fully resting down in the cavity between the frame tubing. It was sticking up about a half an inch. I think the tank was partially resting on the airbox, and not fully seated on the frame, causing it to seat at a slight angle. I think this may have stressed the tank. I have since fitted the airbox so that it now is below the level of the frame. I am hoping this solves the problem. Anyone have any pictures or comments on this? Thanks!

I have a 1971 Alpina...The wheel is centered between the forks by about 1/4 inch to the brake side. I might be missing some spacers. Has anyone encountered this problem?
