radiator frame Gasket?

Is there a gasket between the radiator shroud frame and the chassis frame on my 55.1 GMC-100?

After checking through a few books of mine I am not finding one and don't want to screw up any alignment issues with my hood / fenders?

Classic parts shows a kit:
(1955-59) Radiator Support Mounting Kit
Its just bolts and flat rubber washers. You could probably get the parts at a local hardware store and make your own.

Thank you nrdone!

I found what I needed on Ebay, and yes there are 2 pads required on a 47-55.1
between the radiator frame and the chassis frame.

The last time I had the front end off my 48 I think I used a section cut out of a two ply tire sidewall to make the rubber pads.

Re: radiator frame Gasket?

when I did mine I got rubber washers and bolts from Ace hardware. I think I spent less than $10.00. I also used nylock nuts to adjust in some free play

47/early 49 have a U bolt in the middle and springs and a plate on the bottom of the springs.

They are the same square rubber pads that are used on the bed to frame mounts.
Some manuals have different thickness' to get the alignment of body panels to line up. Most I've read just add fender washers.
