I haven't used those particular bushings, but I have use other polyurethane suspension parts. I like them much better than rubber. They last longer, suffer less deflection and the rubber on some replacement parts you get these days is suspect, showing oxidation and cracking after a few years. I particularly like the energy suspension polygraphite bushings if they're available for your application...self lubricating...high quality.

Haven't used them either. Couple things to keep in mind - the 64 has the front half of the front leaf spring shackle bushings integral to the frame, and can be a royal b.i.t.c.h. to remove. Second, rubber parts are outsourced to golly knows where these days. Some are good, some aren't. I'd sure hate to go to all the trouble to replace and have them fail right away. And that's what "fake" rubber does.
I spent a pretty good chunk of change on springs and labor and the rest of it for my truck. If the bushings give out prematurely because of ersatz rubber parts I'm gonna be pissed. From that angle, if the quality is known to be good, either would be fine. My guess is the poly parts may be the way to go going forward.
