Radiator support

[summitflier]

Anyone have a good picture or diagram of how
the radiator support grommets fit to the frame?

[michael bustamante]

lmc catalog has a good reference. at least i think they still do

Depends on the year of your truck, this is a 69-72 version.

(Don't mind the rust and cobwebs...) Rg

the 67-68 is basically the same except that the rubbers are more like hockey puck shaped

Thanks... exactly what I needed. I saw the LMC diagram,
it has all the parts, but it doesn't show how they assemble together.

I'll add this, there's a LOT of confusion about which grommets to use when swapping things around. Well, I just mounted a 68 chevy support and 68 chevy grill on my 70 jimmy and I used the 69-72 grommets. They looked like what came off of the jimmy so it's what I ordered.

Some people will say to use the grommets that match the core support, but I feel you need to use what matches the year frame you have. At the very least, that is what worked for me.

Good luck, Roger

I have this job coming up. Don't forget about the square washer that goes on top of the radiator core support. Your carriage bolt fits through it.

I think I have a pic on photobucket....I will look for it.

I guess I don't have that on photobucket.

This one looks better though.

He's right, the square washer goes on top of the core support.

Here's my old bolt and washer.

My square nuts were crap! Passenger side it was rust-welded to the carriage bolt head and I had to grind the bolt head down to the washer to get it off.

You got that right! They were a bear to get off, I had to hacksaw the one on the passengers side off after tearing away the old mount.

That's bad. Well my core support is simply too far gone rust-wise to save. I am going to haul it off to the junkyard along with the passenger side inner fender. The rust was so bad where the inner fender and core support are bolted together, the core support broke around the bolts when I was trying to remove the nuts! I ended up using my Dremel Tool and cutting wheel to separate the two.

I should dump the outer fender on that side also but the rear of it could still be a patch panel for someone.
