that is the ring and pinion i plan to purchase. i see it doesnt come with a bearing to install on the pinion shaft... shouldnt i need one?

rumblefish, i have looked into those lockers as well... the suregrips are fairly cheap. but i was thinking that if i NEEDED to purchase a posi style unit that i would go with an aussie or spartan. theyre both priced equally.

i have not yet dyno'd the car... but i dont feel like im pushing an excessive horsepower numbers, maybe 300ish when i get it tuned properly. so i dont feel like i need top of the line parts
