thickness of material under the radiator support

[Bobacuda]

I've read on here that the correct thickness of the rubberized material under the radiator support is essential to lining up the doghouse to the cab, maintain the proper spacing between the doors and the fenders and such.  When I took my truck apart, there was essentially nothing other than dirt under the radiator support. How thick does this rubberized material need to be and where do I find it?

 

Thanks.

Never had any under mine either...can't recall I put anything under when I put t back together either. My fenders fit great and lined up right as rain... But probably best a thin piece goes in there

Two of mine had 1/4 inch thick rubber pads with heavy threads in it.  Like used under the pickup beds.  They were approx. 2 1/2 inches by 8 inches.

My radiator ('51B3C) had two flat washers on each bolt between the rad. and its support.

all that I am familiar with are hexagon shaped cup washers with rubber insert....

I had steel washers under my rad support...no rubber

Yep, now I remember... Washers here too

Wow, glad I'm hearing this now before I got even further along, I have 2 thick round rubber pads. just looked up a diagram an no rubber pads shown, but also no washer between. opinions on what seams best?

I'd go with the washers... Not really an area you need movement in

Sure you're not thinking of the square rubber spacers that are in between the brackets that are attached to the carriage type bolts?

 

They are tucked between the two L shaped brackets inside the upper rear aspect of the front fender that attach to the cab. If those thickness' are off the alignment will be affected.

 

In a lot of cases, those rubber spacers are flattened, detoriated, or just plain missing.
