Hello. from the 1990's.

The Trumpet arms are too wide. It's been done before but not without major surgery.  The needle roller bearing seats have to be cut off and rewelded further in to narrow the pivot point down to fit in a slingshot frame.  

Better off getting a vfr arm as they are narrower and can take a Trumpet hub/spindle/sprocket carrier.

You'll have to modify your frame as most single siders have offset mounts for shocks/knuckles/dog bones.

Lot of work involved taking width of arm. Trim arm, deepen bearing housings, shorten bearing spacer. As JD says, it's easier going for the VFR arm, and fitting the Trumpet hub. But ... do a bit research, as I believe the later VFR arm is more suitable.

Thanks for the advice,    

Its approx 50mm wider than the original gsxr arm , just curious as i have a complete 955i back end,  i have seen a few pictures online but no real detail,  i work in a machine shop so cutting and welding might not be beond the realms of possibility.

I machined a new pivot / machined the arm and centralized the wheel / machined hub for chain run....., very doable and looks better than the vfr swinger

That's a really nice job.

Did you do this on a bridgeport or cnc ,

Any drawings,  cad files , dxf files ?

so now you know it fits...... start a build thread and I am sure with the collective minds on here it will be just fine
