Delrin, is a bit softer, and will deflect more than Nylon will, but MUCH less that the stock rubber mounts do. Nylon bushing will have a tendancy to squeek becasue of their hardness and limited "self lubricating" qualities. Delrin is very slippery compared to Nylon, and is very close to Teflon in this regard. I chose Delrin when I made my bushing. I bought 4' feet bar stock from a local platics distributor, this was in 1977 and I believe it cost me about $20. I removed the original rubber bushings, burned the remaining rubber out of them leaving the inner tube and the outer press fit case intact, and polished both peices to a very smooth finish. I then used a lathe at my high school to turn down the bar stock into these custom bushings that pressed into the outer case, while allowing the inner tube a snug but not tight fit.
They actually worked very well, and didn't transfer a lot of road shock through the rest of the car, but they were much stiffer than the worn out rubber ones were!
