I'm in the process of mounting the grill, splash pan and bumper on my '54 Chevy. The PO had removed and discarded all the spacers and bolts from under the radiator support (ithe front clip was was just sitting on the crossmember with no bolts). I don't know how many spacers had been there origninally. The Factory Assembly Manual states "shim as required". I bought bolts and rubber pads from Classic Parts and installed them. Things are not coming together right, there is insufficient space between the bottom of the grill and the splash pan. It looks like I will need a half inch or more of additional spacers under the rad support, that seems like a lot to me. Not sure what to do next. Anyone have some good ideas? Don
