Kz750 swingarm swap need a little help.

I'm new to this forum so first I'd like to say hello. I recently purchased a 1978 kz750 with low miles for 700$. I thought it was a good deal considering it runs perfect and is in mint condition. The only problem is the guy that had it last tried a swing arm swap. Basically he took the stock arm cut it and welded Suzuki gsxr ends on it. He was trying to switch to crotch rocket tires and rims. After I bought the bike I noticed he wasn't the best welder decided to go original. Reason being is he sucked at welding and I would have to really mod the bike alot. I would have had to switch to single shock in the rear end an welded up multiple flat plates to support it. Anyway the biggest problem I'm having is reassembling the rear hub and swing arm. The front pivot part of the arm in intact but the rear came disassembled. I have all the parts just don't know how they go. I also have a book on the bike but it gives horrible descriptions. I'm used to working on dual sports and this bikes throwing me for a loop. Thanks for any help anyone can give me.

Hello, B-Niles, and WELCOME to KZr!

Lots of good info on kawasaki.com, including parts diagrams, part names, part numbers, models sharing same part, availability, etc.
