Good to see the old Bonty is going well, heres a picture of it in Utah on the Jem trail
As for the forks, Tim at Pace removed the air cartridge, which are renound for leaking and replaced it with a spring set, think he did it to a few of the early RC36's.
Basically there are no elastomers in there, just springs in both sides, they are easy to strip and service, just remove the cir-clips at the bottom of each leg and slide them apart. Probaly need a good service and if you don't feel confident, ring Pace and ask to speak to Tim, best be quick though
He also frequents this forum, so watch out he might even add to this post
