A arm bushings
Hey guys I purchased poly A arm bushings for my 78 restoration. I took the bushings and A arms to a shop to get pressed in. The shop damaged two of the bushings. I have to purchase another complete poly set just for two bushings. So should I continue to go with the poly or should I just go ahead and start over and use rubber bushings. What are some of your all experiences. I’d love your input.

Agreed, should be no reason to damage them on install. thats the easy part. I like the poly. remember to use loctite on the bolts.

Doesn't matter to me what you do, but in the old days, the Corvette racer, John Greenwood tried urethane and rubber bushings. His test findings on the track were that it 'seemed' from the driver's seat like the poly bushings were faster, and they were definitely stiffer, but the track times didn't improve any and there was a higher incidence of failure (not significant) so he stuck with rubber. Course urethane formulations are probably better these days.
I definitely wouldn't take them back to the same shop.
Maybe you can buy what you need for replacements onsie-twosie off ebay.
Good luck
