Prothane radiator support mount - The 1947 - Present Chevrolet & GMC Truck Message Board Network

joel.e · 08-24-2013, 08:55 PM

So I have the Prothane kit for '67-72 but the radiator support is a different diameter. The urethane mount is larger than the OE hole in the core support bracket on the frame? I searched but didn't find anything. Guess I'll make the frame hole bigger...

What year truck do you have?

Chevys10dr · 08-24-2013, 09:14 PM

I has the same set, mine were about 1/32 out, I just took a carbide and made it fit snug. For got to add my chassis was a 68 2WD SWB But the body is a 71

Check out the differences in the mounts.67-68 are different than 69-72.I don't recall the exact differences but someone has listed which to use when changing front sheetmetal.If you use the wrong ones the front sheetmetal will never align properly.

Is there a difference the same using stock mounts when using 68 frame and 71 body, if it is that explains the slight misalignment the PO did alot of messed up s*** to the truck.

The box indicates they are for '67-72. Guess I'll make my frame mount bigger like Chevys10dr but mine are closer to 1/8" to small.

Thanks for the replies

i would not use prothane mounts for a street driver vehicle ever again/// most guys with daily type triucks dump them within 3months of installing them

I agree, stock rubber type are the way to go. The Poly ones tend to squeak.
