Which swingarms will fit a 1978 GS1000?

[Old Guys Rule]

I just picked up a 1978 GS1000. I am thinking about upgrading the tube swingarm, but can't find a Cal Fab or JMC. I wanted to know if there is a bolt-in and ride solution from a newer model, such as a GS1100 or Katana.

Both GS(X) 1100 and Kat twin shock swingers slot straight in.

gs1000 with gsx1100 swingarm,,,,

hi i,ve got a 1980 gs1000e,,, and a few years ago i purchased a mint condition headlight ,,the guy sent me a box,,, with all the stuff in it ,,,,which included a gsx1100 alloy swing arm .... ..last year i cleaned it up it was provided with new seals so i re-greased the bearings /shaft and its been happy since ... a great improvement stops flexing .. regards oldgrumpy

What about a 78 750, same deal?

Close, but the pivot bolt is thinner on the 750.

You have to drill the frame (to use the 1100 pivot bolt) or use tophat reducer bushes for 750 I believe.... Cafekid has done it & posted on here somewhere.
