Well, you don't want the shock to be a bump stop. Where is you lower mount? I would do the same as post#2. You need to know your travel... distance from fully stuffed to fully drooped. I don't have a pic handy, but mine looks like Joes (except I do'nt have those nice shiney Fox's. lol.)
It's all relative. The mounts, upper and lower, need to match the length of the shock, including the length of the can, the travel, ect. You may have to adjust your lower mount to match the MORE upper. That would be my guess.
