lol trust me I have bought almost everyone the hardware store has. The strut gets skinnier at the top half so I used a o-ring there and then just rapped tape around it till it was hard to get the sleeve over. Then I made two make shift o-rings out of the tape bellow it. Both sleeves sit slung on the strut and there is no movement, just like the front ones so it looks like this was a sucess. I might install them this weekend, but I have work sat. so we will see.
