The Kimpex 04-269 is discontinued, and the parts distributor now lists 04-269-01 for Invader 78-81. Previously, 04-269 was listed only for 78-80. (excluded Vari Ride) The closed and open lengths are longer for this shock vs 04-269, and the eyes are 29/32 on both ends. It looks to be the same as SPI SU-04282. Is it useable with the longer lengths? If so, how do I get a rubber bushing and spacer into the eye on one end?
