around town you might need to run it in 3rd gear. 3.42 would be my choice for a rear end gear.

^X2, this would be the ideal setup with 3.42 and the rest as above, and as mentioned watch the TV setup make absolute that it's correct, otherwise you'll possibly end up with a junk tranny, as for the town driving, just have a lockout or override switch so it won't go into 4th.
