The same as item 12 on this page in the LMC catalog http://www.lmctruck.com/icatalog/ca/full.aspx?Page=81

I don't know how thick those are but I made the radiator support pads for both my 48 pickup and my 51 Mercury out of the sidewall of a scrap tire when I put them together. Both were subframed with first generation Camaro subframes though.

I used 1/4" thick dense rubber used for flooring in horse trailers. Locally it is sold by the foot. That seemed to match the old compressed stuff that was there, BUT I have not hung my fenders or hood yet so do not know it I will need to adjust it. I used the same stuff for my cab and bed mounts too.

similar to orrieg; i used 1/4'' rubber from a bed liner mat i had cut a piece from

They are about 3/16 to a 1/4 thick and it should have 2 flat washers that the bolt goes through. The support isn't clamped down tight, its snug but floats on the support pads

That is a real good point that too many guys miss and a lot of us figured out the hard way. When you have two pads sandwiching a piece to hold it down you don't want to tighten the fasteners so tight you completely compress the pads or bushings. Shock bushings on stud type shock mounts are a prime example.

original had a tube spacer on the bolts so that you couldn't over squish the rubber

OrrieG · 05-04-2014, 10:16 PM

Ogre, good to know, I missed that but can still add them. I don't recall them being there when I pulled the support and they were not in the parts baggie, but I know one fender had been replaced and the lower valence was bent so maybe they got lost during previous repairs.

factory assembly manual sect 13, sheet 14.00 if you have the book

OrrieG · 05-05-2014, 04:34 PM

Yes it is! Some how I missed (or forgot by the time I got back to the work bench) that when I looked at the page to get everything in the right order, I even had it tabbed in the book for quick reference.
