Gotta a quick question. I have 3.27's on my 96 however, i am finding the fact that they are not trac-lok'ed a little frustrating. My girlfriend works at AutoNation which in turn over here owns one of the ford dealerships which gets me employee discounts on cars and parts. So i guess my question is that i want to switch to 3.73's with trac-lok so which would be the best pumpkin to get since i can get discounts? Would the 99 cobra pumkin be the best or is there one better or all they all the same? Thx for the info.
