Look on the backside of the plate on the forks, usually the left upper area, that is where they put the ID decal usually if it survived. I believe that version was a model 90 or MB 90 something like that. Nice big riders the big wide bars are ugly but comfy, the sissy bar kinda digs in your back though if you have long legs but does kind keep you in/on the bike. stretching the seat mount and inch or so during the build might be beneficial, that was my thoughts on the one I had anyway.
