procomp distributor–no gear??

Hey guys, I'm a bit confused, a newbie, but through my experience aren't all distributors supposed to have a gear on the bottom. I called procomp and they said for chrysler it doesn't have a gear. This is BS right. I mean when I look down the hole on my 340 I see a receiving gear, so what can I do? I have the procomp 8006 distributor, does anyone know what gear I can buy for this distributor. Thanks guys[-(
