Exhaust manifolds-what do they fit?

[oldcarnut]

I have some manifolds I want to get rid of but I don't know what they fit.  Is there a part numbers search I can look them up somewhere?  All I know they're big block.  Cast numbers are 253246(8?)4, 2463107, and a pair of 3769103.  Can anyone help? Thanks, David

The 2532464 is right side '66-69 B body, C body or truck 361, 383 2 bbl, or 440 ALL low performance, the 2463107 is left side '65-69 C body, 383 2 bbl or 440 LP. Can't find the others, sorry.
