Grateful for any input
I don't know about the 990 rear shock but I know on mx bikes there is a peening on the shaft for the valve stack to prevent the nut from coming off, that would require grinding. Good for you taking on this task, once I figure out what needs changing on my forks I am going to do it myself as we'll.
Also when you mean stretch, you mean increasing the travel?
+1 talk to James at superplush, 9X0's are his specialty. He won't hesitate to tell you what you will need, and honestly you may only need a spring or a preload spacer the rear is way better setup then the front.
