'65 Chrysler Steering Donut Heat Sheild

[rexus31]

Does anyone know the correct diameter Corbin Clamp used to secure the heat shield to the column? I think it is 2" but I am not certain.

As far as I know, the heat shield screws to the column with 3 sheet metal screws. All my 66s are like that.

Otherwise you'd have to disconnect the column if you ever needed to change the corbin clamp.

I believe they made that change for '66. I do not have any screw holes present.

What does the service or parts manual show? I'm intrigued, as I parted two 65s and don't remember a giant Corbin...

Just had to replace my shield last year (65 Dodge), as it was missing. Hard to find, most got tossed long ago. Never could find a good close up diagram. Not so sure that these were retained by Corbin clamp. I know it's not correct, but I found a double wire style screw-retained radiator clamp that fit perfectly! Hid the screw on the bottom.

Agree that there was running change from clamp to screws, sometime in mid-late 65.

Interesting.

That heat shield is most necessary to prolong the life of that rubber donut - it's proximity to the exhaust manifold is a killer.

Definitely a clamp on mine. Not sure of the size though.

I couldn't find a pic in the service manual.

I'm pretty sure 65 Polara is same as Chrysler....... so here goes.

A standby from the stash.

Couldn't find my calipers, so this is it.

As installed.
Hope you can use these.

As per Polara 500, I believe this is the correct clamp. But you're going to have the column disassembled . . .

Just had an epiphany so went and compared with a kit I have on hand - the large corbin in this kit is the same as the one holding the heat shield on the column.

Lower radiator hose is 1 3/4

Those pliers would make it a lot easier than these

Yup, and they also lock in place, holding the Corbin clamp open. One of the best tools in my toolbox. Pliers can actually nick the clamp surface, which can cause them to fail. I thought they were long a "vintage" tool, but one can still purchase them.
