Replaced failed strutrod poly-bushing today - Took video of working suspension

The Delrin LCA bushings are made by Peter Bergman, Bergman Autocraft. Also known as GmachineDartGT here. I know he's been using the Delrin LCA bushings for years.

The poly bushings I've used in the past were just Prothane Motion Control 4-205-BL. They're just the bushing, no shells, and they're like $12 from summit. https://www.summitracing.com/parts/ptp-4-205-bl/overview/year/1974/make/plymouth/model/duster That's the set I just pulled out of my Duster that looked brand new after 12k miles. I think I have about 14k miles on the set in my Challenger. The downside is, they have to fit that outer shell. Hotchkis makes a set that looks identical, not sure if they actually are the same or not. Those cost $29. I use that style with a greaseable LCA pin I get from Firm Feel. Although I think PST and Hotchkis sell them as well. Lots of poly grease and adjustable strut rods are the way to go with those bushings.

Proforged is making a poly LCA bushing now that has inner and outer shells installed already, just like the originals. Not sure if they use the same friction fit on the bushings material. But they'd install just like the originals, and you could use the original LCA pins. I have a set, haven't used them. Was just curious. They can't be greased, so, if they aren't a friction fit like the originals they might have an issue with squeaking. But I don't know, haven't run them.

Anyway, long answer. The short answer is that I source my suspension parts from everywhere. Bergman Autocraft, Firm Feel, Hotchkis, QA1, Dr. Diff, etc. I cherry pick from everybody. I buy most of it through Summit Racing, except the stuff from Peter and Cass, their stuff comes straight from their websites.
