No, you phrased it correctly and I replied "they rebuild alot of stock shocks". Seriously, give Lindemann's a call. Or maybe Race Tech too. I know Lindemann's can do things like new/different springs on old shocks, recharging the nitrogen, titanium nitride coating of the pistons/sliders, reannodizing and basicly make an old shcok look like it just came out of the box.
on my 86 750 I put a 90 or 91 style swing arm on and used a 91 or 92 I think 1100 shock. Its the 40mm showa big body, then put gold valve in it it works awesome. Had to modifiy the fork mount on one end of the shock to an eye mount and remove the eccentric from the stock shock linkage and made new dog bones and do a bit of grinding to clear things.
