PROTHANE 7-1711 Red Urethane GM Style Small Block Engined Radiator Isolators

First off let me confirm these fit my 1976 Chevy C10, with a caveat. I had to trim two down to fit the top rad mount.Other than the two that needed trimming to fit (used hacksaw to trim excess), these fit everywhere else perfectly, and the old rubber isolators the truck had are so worn out they allowed my aluminum radiator to hit and rub the rad support. These solved all my rad mounting issues. They hold the rad so much tighter, and put it exactly where it needs to be.If you think prothane is just for suspension, think again, love these, only way they could have gotten 5 stars was if i didnt have to trim the top 2

Did not fit my c10 and are not as pictured. I needed what was pictured. Had to cut these up to make them half way fit and they're still junk as far as I'm concerned. Not sure what they're for but it definitely wasn't for my application as it said they were.

Good fitment

Size for my small block radiator was a little off and I had to modify them to fit properly on my truck but once cut they are not moving and will last a while I feel.

Got these from Amazon warehouse, as described. Not much to them but they are made of a dense material which I don't expect will crumble any time soon. I prefer rubber for body mounts but these should be great for a radiator.

the feel of poly is much better than rubber, cant tell you right now how great the product is , im building my car like johnny cash did. ill get back with you if i finish and can still review.

They work perfectly,but had to trim them slightly due to aftermarket aluminum radiator. Highly recommend to all.

Didn’t capture the radiator as tightly as I would like. Used them along with some rubber strip and got it done.
