Rad support question

[fireguyfire]

I’ve blasted and painted my “U” shaped rad support and I’m getting ready to re install  the front clip of my 1940 1/2 ton.

The rubber insulator that goes between the bottom  of the rad support and where it bolts to the frame is long gone.

Is the rubber insulator that goes there a thin rubber piece (1/16”) or the thicker style (1/4” thick). I see both available on line and it’s impossible to tell how thick it should be by the drawing in the parts manual.

My truck has a piece of semi mudflap we found at the curb. Been working great over 20y. I'd say you need the thicker stuff

I’m curious, as DCM sells the thinner one only in their kit
