2 964 window regulator questions

[Adidas]

2 questions on my driver's side window regulator 1993 C2 convertible.

1. window height adjustment. Don't see any adjuster with door panel removed but I'm sure I'm just not seeing it

2. What year convertible regulators with fit my 1993 964. Will earlier 911 regulators work?

There are adjustable stops for both up and down on the arm. Can't remember exactly but the is a position and an opening that will line up for adjustments.
I think the 964 part was a later update to fit the earlier cars but don't know for sure if you can go the other way.
By the way, I think the coupe and cab units are the same??

Usually there is only one stop on a regulator. It is on the bottom/open direction. The glass to frame to is usually the up stop.
