This is the red polyurethane fullsize 65-70 Chevy bushing kit I tried a few years ago, Summit #ENS-3-3150R. (I just used the 4 upper control arm parts and tossed the unneeded larger bushings on the shelf).
They deformed badly....the urethane was actually pinched and squeezed out of place, as if the upper control arm had an unusually heavy force pulling it away from the engine, parallel to the ground. Wish I had taken a picture of that before I removed them. Never really understood how or why that happened, as the rubber units in there now are jsut fine. I know these were specified for a 65 fullsize Chevy, but would being designed for a strut rod front suspension really make any difference?? They sure didn't seem to be any softer than any other poly part I've used, and I did use that sticky lubricant that came with them.
