I know this might be a stupid question but.......are the replacement bulbs 9004 or 9007? I have a 88 gl wagon that I am ordering headlight bulbs for, but don't have it with me right now to check.

partsamerica.com says its 9004

Yep, 9004

Probably too late, but you could do your eyes a favor and check out Sylvania (OSRAM) Silverstars or better yet UltraVisions. Here is a link
