Switching 1963 valiant wiper assy to 1965 questions

All i done to my 63 Valiant was pull the firewall back about an 1 and half till the disb. fit and still used my same wiper motor and everything else,And it work just like always,JUST SAYIN took about 30 mins.

I did that also on my 63 valiant 25 years ago.

But we had a 65 parts car, and wanted this project to come out as clean as possible. I have no regrets about swapping firewalls.

Just have to figure out which pivots work with which arms
