Hmmm... I clicked the email button and it said you've kept your email private but it prompted me to type my email in a text box and told me it sent it...
Anyway, I didn't want to advertise on the site, but I was writing to say that while I didn't have the answer to your question (because the car is at my parents' house right now) I have a stock fan a '68 LF7/PG non AC with PS car if you're interested. I also have the spacer... I'm using it at present, but I don't care so much about originality so if it will help you out I can just get myself a new one and you can use my old one.
Email me at [email protected] and put something about "Camaro" in the subject so the email doesn't get caught up with my junk mail.
- '68 Chevy Camaro (sort of done, but always subject to improvement)
- '63 Pontiac Tempest (work in progress)
- '72 Datsun 240-Z (back-burner for now)
