I just saw your message and I am in the same predicament as you were my friend. I also owned a 1983 GPZ 750 and I do want one as well well. I am hoping that if you see this comment you may get back to me and let me know how you made out…. I have only been able to find a couple of them in very good shape through some auctions. But nevertheless I am still looking… hope you found yours !!!!
