Hi everyone wasn't sure where was best place to post but I have what I think is an Ellsworth Isis 2002 19" frame which has been custom built to preference problem is the rear shock can't find anything to fit at all been looking for months, only things I can find what could fit are ancient posts there's Romic shocks and 'push tuned shocks but can't seem to find any anywhere can anyone help me out point me in the right direction or luckily have any for sale? Cheers pics below of the bike

not sure of dimensions, but I rode a similar vintage Ellsworth Truth, using a now (obsolete / legacy) 5 Element Shock ... dunno if worth searching for one of those via eBay?

Yeah it gets mistaken for a joker but jokers had two rear shock mount positions,spec sheet says 6.5 x 1.5 rear shock size uses threaded m6 bolts it's just the bushing diameter which is the problem can't find a shock that fits unless I can buy DU bushing reducers on a compatible shock which is also compatible with the frame lol, turning out to be a right headache.
