      Rubber Bracket

      The upper rubber brackets worked perfect. The bottom insulators needed modifications but ultimately also worked out for my needs The insulators help support an enlarged radiator ( 3-rolls) for cooling a 1989 5.0L installed into a 1965 Mustang.

      No Different Than Stock

      I checked these side by side with my originals and couldn't tell them apart. Fit an function is exactly like OEM. IF you're already swapping the radiator don't just reuse the 30 year old insulators. These are inexpensive and fit great.

      Radiator support rubbers

      They're exactly the same fit as the old rubbers. They hook in so there's no movement when installing the radiator. They fit perfect.

      nice product

      the reason i didn't give this 5 stars is that I didn't have the originals in, the car the previous owner took them out , when i got the new ones they have to go in a certain way ant there was not a diagram so it took a few tries to get it right

      Good but needed modifcation.

      I bought these to go with my new radiator. The only catch was I had to modify the bottom insulators because I purchased an aftermarket radiator. I had to trim a portion of the bottom insulators to make them flat all the way across. This is so my radiator would not sit too high, in order to give the fan enough clearance to keep from contacting the bottom of the fan shroud. Once I trimmed off the excess sections, the radiator fit perfectly giving the fan enough clearance from the shroud.

      Exact replica

      These rubber isolators were exactly like the original Ford ones. They even had the OE Ford part numbers on them. Perfect fit with the new radiator.

      Good quality for oem replacement

      When I replaced my stock radiator with a Griffen 4 row aluminum radiator, I had to modify the driver side lower insulator in order for the radiator to sit properly. They worked perfect with the oem radiator but be prepare to modify if you have a aftermarket radiator. Excellent quality though.

      Perfect for Restoration

      My old radiator had it and so did the rubbers on the support brackets as both were stock from 1988!! These were a perfect fit and just what I needed to keep the radiator from vibrating apart. Shipping was fast as always and pricing low!!

      A nice replacement for worn OEM pieces

      Picked up a set of these when I put a new radiator in, the orginals were quite worn after 21 years
