Gear ratio

It does indeed say A03A. Earlier in this thread someone posted that the tire size the sticker states may be incorrect so I wasn't sure if the gear info might be as well.

I am restoring mine to be "built for comfort" and to haul a travel trailer that weighs approximately 3300lbs. I wonder if I'd be better off regearing to 4.556? I'll mostly be traveling highways and interstates. Off road usage will mostly be limited to forest service roads and other non-paved roads to get to trail heads.

Another way to verify - you should be just over 2k RPM in OD with the torque converter locked at 70mph with those tires and 4.10 gears.

If you are pulling a trailer that heavy, you should have OD off anyway, so your gearing should be ok. If after a trip or two you find it doesn't work well for you, then re-gear. Also, watch those trans temps...

Yeah, phase two after I do a lot of maintenance work is going to be getting gauges setup for AFR, EGT, tranny temp, water and oil temp, etc. The end game is to eventually install a SC but I want to have everything else done first.
