I think we have this question successfully answered except for if it perhaps also applied to Star Chief models?

Any additional last-moment insights before we go to press?

Thanks for all the positive input. The Pontiac hobby is wealthier and healthier because of it!

This thread a little old but I have some info I can share with you.

I own:
#1 - 65 Pontiac Laurentian wagon (built in Canada)
- parallel wipers

#2 - 65 Pontiac Catalina wagon (built in US)
- HAS THE TWO-SPEED WIPER OPTION
- C16 on body tag
- 421 code on build sheet
