85 GPz550 Tank and Upper Fairing

Started cleaning my tank for paint today. After the paint and rust were removed I found the lower front section looks like swiss cheese. To make matters worse when I removed the upper fairing the entire mounting lip on the right side is broken off. Kind of bummed since I just got to where I can work on this bike again. Does anyone know what tanks and fairing are compatible between bike? There's just not a lot of used 550 parts but there's a ton of GPz 750 parts, will these bolt up?
