What is the best way to identify a radiator support? Should there be a number stamped somewhere on the support? I have looked for a number on it and don't see one. Is there a significant difference between the big block radiator supports and the small block supports? Are there any significant visual differences between the two that I could look for to help me identify it? If there should be a number, maybe someone could tell me where it should be. Also, I am getting ready to put the body back on the frame. I ordered a new body mount bolt kit and noticed that there is no rubber cushion to place under the radiator support where it mounts or sits on top of the frame rails. Should there be a rubber cushion that goes between the frame and the radiator support? Thanks for your help.

Re: 66 radiator support
Shane,
Long Island Corvette lists 5 different radiator supports for 66 cars; one for early small block cars; and then different supports for 327 and 427 cars and different ones for cars with adn without AC. So, this indicates that '66 BB and SM supports are different. I've got an NOS support for my '66 small block, non-A/C car and other than a sticker with the GM part number, I'm pretty sure there isn't a part number stamped into the support. I can take a closer look when I get home tonight, but I'm pretty sure that if the sticker is gone, then you have to identify the different support via configuration differences.

Re: 66 radiator support
Shane and Gary-----
There are no part number stampings on most Corvette radiator support assemblies; I don't know why. Although there are several slightly different configurations, there are 2 basic configurations. The basic small block configuration can be easily identified by 2 brackets with cup-shaped recepticles welded to the lower rail of the support. These serve as seats/mounting points for the lower mounting pins/grommets used for the aluminum radiator supplied with all small blocks. Big block radiator supports have 2 "U"-shaped braclets welded to the lower rail and these are spaced further apart than the cup-brackets used on the small block supports.
From the above, you can see that the small block and big block supports can be discerned at a glance. There are a few further variations of each, though.In Appreciation of John HinckleyComment

Yes, they were - the (black dip-primed) radiator support was installed in the Body Shop as part of the raw fiberglass front clip subassembly.Comment
