Note: The winder in this page is NOT a GT Hawk part. More likely from a 62 Lark. See Window Regulators
Side A Side B
The third photo is of an Avanti manual and electric winder and as you can see the only difference is the winding mechanism itself and the location of the spring...
I removed the pin as shown in the fourth photo and replaced the winding mechanism from there although you could probably do it further down.
