The gear is uneeded with the aluminium quadrant. It's there on the stock unit to give some adjustability but you might as well get a firewall adjsuter which is much better and less prone to wearing out like the stock unit.

you don't need the pawl with any aluminum quadrant, regardless. i have the pro-5.0 quadrant which has only one hole. the other side rests against the second post that the pawl used to go on. SOOO much easier to install! and the firewall adjuster that comes with it is NICE. here's a pic.
It's no biggie - the end result is you don't need the POS. Imagine if you were still needing it................. and all the swearing when you tried to install it. Kinda sounds like something I'd do (I'm really big into mashing round pegs into square holes).
