Webside for old Chevy Parts

[Geri]

Hello everyone!

I have a question about old chevy parts:

I bought me an Factory Assembly Manual for my 1953 Pick up to help me by restore. Every Part in this Manual has a special Number (for example NUT 043469).
Do someone knows a webside, where i can get Information about this old chevy parts? It´s better for me to get more information about missing parts, bevor i order it in the United States........ it often takes a long time

Thank you
