How hard/expensive is it to switch out gearing on an A-body?

I agree again!! If he can buy everything at the prices you quote it would be great but he'll be limited on gearing for his highway cruising. I get great gas mileage in town as well but "svevobandini" will surely make a decision that best suites his needs.

i hear ya, dont get me wrong, I'm doing a TR6060 swap into my dart for that very reason, but when you get into swapping transmissions to modern ones, you start talking about big bucks, mine will run me close to 2500 bucks using a junkyard sourced TR6060. I imagine a 2004R is gonna be at least 1000-1500+ not counting adapter plates and such.
