Taller Tires Needed

[junkyardhero]

What pinion would it be for a 30" tall tire? A 30 pinion? That's what height tire I think I'm going to go with. Where can I buy these speedometer pinions??

you'd need a 30 toofs gear.

here's the info courtesy of brewers: Brewer's Performance - Mopar A833 4-Speed Transmission and Component Specialists

the gears come up here used frequently, and you can find them easily on the web. i know brewers lists them. i don't have one or i'd totally hook you up!
