Another trailing arm bushing question, Polly bronze durable? Options

[trojanhorsepower]

I relatively recently installed my new set of 914rubber bushings. These were purchased maybe 10 years ago and installed maybe 5 years ago, but since the car was apart they have almost no miles on them. After finally being able to drive the car I found this.

So clearly these don't fit properly. I was going to go with the Elephant racing kit, but a friend of mine installed poly bronze bushings on his Jeep and they did not last a year. Anyone have any experience with these bushings as to long term durability? Or should I just bite the bullet and go with the soft rubber original style?

Thanks,

Peter

I have polybronze in the LS car with about 6000 miles over 5+ years and they're fine. You need to keep them lubed - I think the service interval is every 5000 mile but check with the mfg. I believe it's a requirement to add zerk fittings to enable lubrication without disassembly. In looking at your videos, I didn't see any zerks so maybe those weren't maintained as needed?
