Havent bought anything in awhile , but when I did 10-6 yrs ago....I found Ames to be the best,bought most from them, bought alot from Classic, but had to figure out first if it was a FB/Camaro part or FB OR Camaro...(`Maro spoilers fit fine! lol)
bought ONE item from Year One , as they seemed the highest priced and had one part nobody else did...bought a few from Paddock...only tried once at NPD (inner ws pillar covers for vert), and the part didnt fit ,was returned (got nice used ones from FirebirdBill instead) and I never tried NPD again...last few yrs I check Ames first.
