Nothing swaps over from a donor without some effort.
The wheels off of a GS450 will bolt on, but there maybe issues with the rear hub and the disk will have to be modified.
The front end off of most GS's will swap over but sometimes it's all or nothing.
There's been a couple of vs800 front swaps and a vz800. both entail work.
shocks off a vs800 go on quite well.
various seats swap, nothing bolts on.
Find something you like, park next to it, and the parts will migrate if compatible.
I keep parking next to a honda fury, but the guy keeps moving it.
