Good Luck! The originals worked very good for a very short time. They were DeCarbon gas filled type but the seals failed almost before you could get the bike home. Even replacements are hard to find now, partly because of the lower clevis mount & short length. Put on whatever you can find but keep the length & spring rate the same or handling will be impaired. Keep the original shocks & show them to after market suppliers, such as Hagon, to see if they have something that can be adapted.
