3.23 would probably be OK, but I don't think that's available for a 12 bolt and I don't want to change whole rear end. I'm leaning towards the 3.08. If I go to a BFG Radial TA tire that's 26.6" tall, that would give me 2528 rpm @ 65 mph. That seems reasonable to me. I don't think I'll be doing much, if any, interstate driving so 65 mph is about the fastest cruising speed I'll see with any regularity.
