I think it also shows that there are some advantages to a car with no radio. Can you believe that this 32 year old car has NEVER has a radio installed in it? The little chrome cover is still there, in the hole for the antenna. > seriously i know i have to sort out my rear right hand side in this respect > as it is knocking and ive narrowed it down to the resiliant mounts with my > stethoscope. If it's knocking, then it's loose, which I think would be the worst possible situation. My 69 is probably the same or worse, but my "new" '71 is in terrific shape. > so when you have done this in the past jim i take it you have undone all the > subframe mounting bolts and then lifted the body slightly of the rear > subframe? I've never done it. It's a pretty scary task that will require some careful preparation to approach. Yes, I think I have to figure out a way to support the front of the rear subframe (and, for IRS, the engine) leave the wheels on the ground and gently lift the body just enough to slip in the newer parts that I have. I suspect the bushings on top of the shock towers will be the hardest to get to. I'd be happy to let you go first so you can warn me about the pitfalls. ;-) > in my never ending quest to get the typ3 i want to handle at 200kph i will > also be replacing the front rubber resiliant bushes with something a little > harder i must admit that last time i posted i was going with aluminium > mounts in these areas well i am reconsidering and need a sorce for some > urethane or such like hard rubber. The front bushings are actually pretty stiff stuff already. There's nothing special about polyurethane except its toughness. Both it and any other elastomer can be made in a wide range of Shore hardnesses, so we'd really have to investigate this in detail to make sure that there was an overall improvement. In addition, I'd worry that if you just replaced these with flat sheet they might well work their way out of there rather quickly. The molded shape of the originals makes for better retention as well as more stiffness. If you wanted to replace them, Devcon makes several castable polyurethanes which you could make a replacement from, but you'd have to make a mold from an original first. The Devcon stuff comes in several different hardnesses, but the stuff I've used was all softer than the OE bushings. I just looked at their catalog and it really doesn't look like they make a really stiff version. -- Jim Adney jadney@vwtype3.org Madison, WI 53711-3054 USA ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ List info at http://www.vwtype3.org/list | mailto:gregm@vwtype3.org
