So I just bought a 1990 gs500e and it needs some work. I might make a better post on the whole build once it starts moving along. One of my main issues right now is that for some reason most off the screws/bolts along the frame are missing(the ones that hold things like the voltage regulator, tank etc.) Is there any type of resource that I could use to identify/buy these? Any help would be appreciated.

Thank you.

They have diagrams of everything.

And for bolts that you can't get from the hardware store, post a WTB in the For Sale/Want to Buy section.  Adidasguy probably has what you need.

When you identify what you need I have a bunch of spare bolts, nuts, spacers and a few brackets.

I have a lot of spare bolts and hardware. I might have something you need
