Moving upper shock shock mounts?

Good point. Buy why make mods if you don't do it better that the original?

I know Im just saying that the fancy jigs are definateloy overkill for something that can be done with a couple good levels and a tape measure.
if your swingarm is straight and shocks are both same length thetres your jig right there

I'm pretty sure that Sanctuary jig serves more purposes than just installing shock mounts - from all the holes and various mounting points on it my guess is they also use it for building swingarms, modding the rear frame, check alignment etc.

I made up a simle jig that bolted on to the rear stock mounts, then bolted in my new mounts, and held them in place on the frame where I wanted them. Used a machinist square and caliper to ensure they were true, and voila, ready to weld. You have removed the original rear frame section so this wouldn't be an option for you.... Just my .02
