I usually call it pinch molding, even though I know it is called somthing else which I can't remember. I get it from the fabric store believe it or not. The rear is pretty simple as far as the cylinders go. Just getting to the top bolts is the p.i.t.a. I will post pics when I get it done though. The cylinders have 3 total seals. 2 round o-ring ones and a polypak. I have had the same seals in my Benz for 6 months, but that is still on the low end. You can expect to go almost 2 years (with everyday driving) before you need to replace the seals. I have seen up to 2-1/2 years on the same seals (on a design we based our cylinders on) and I have seen 6 months. A lot of it depends on how much you use the hydros. On Brandon's car (the 2-1/2 year) he only goes up and down to drive. No sides or 3 wheels... basically set it on the ground and lift it to drive. That is why he got the life out of them. Obviously the more you beat on them, the less the life of the seals will be.
