Model A Metal Glass Channel
The metal channel holding the bottom of the door glass. The regulator arm fits into the slot in the bottom. Right and left are the same. These channels are made out of a lighter gauge steel than the authentic channels (A-45962-OR, A-56787-OR) and required to be altered to work. The "L" shaped piece of metal that is spot welded to the glass channel needs to be rebent so they will properly attach to the regulator arm. Coupes, Tudors, and 30-1 Trucks: A-45962 are 24-3/4" long, Tudor Rears are 28-3/4" long: A-56787
