Purchased a set of four radiator rubber mounts from NPD for a 68 SS396 with a Harrison radiator. They are RED and all four the same size. Checked with Greenwood Chevrolet and they say the parts catalog shows them the same size.

Searched the posts and found the suggestion to trim the mounts.

The originals are larger on the passenger side than the ones on the driver side.

Can anyone help?

they should be the same size. i would look at your core/radiator support, and see if it looks the same on both sides. i have never looked at 68's, but most chevy's are the same size.

The 3 row radiator which was used on the SS-396 Chevelles in 68 used two different size rubber mounts. The left/driver side should be the shorter ones (top and bottom) and the rt/pass side should be the longer ones. I have the the original radiator tanks (recored of course) and the two sides are different sizes thus use different size rubber mounts. I reused my originals when I did my car, but I understand Year One sell the correct kit with two size mounts to accommodate the left and rt tank Harrison tanks.

Also as far as the ones NPD sent you, just the fact that there red should throw up a "red" flag, so to speak. The originals are black. Sounds like something that should be on a Toyota or something.
