Hi All,
I know junkyards can do it, but is there a website I can go to to see what parts are interchangeble between production years and vehicle types? It would really help me upgrade my truck on the cheap from e-bay and the "u-pull" junkyards.

i.e. can seats from a '93 C1500 fit a '99 Suburban? (and similar stuff)

Thanks in Advance,
Sir Veyor
