Nick,
mine was also a 6 cyl. It came with 28 spline axels, also had the big bearing housing.

My Custom 300 was originally a 6 cyl. I'm not sure about the size of the bearing housing, but the original 3:70's are still in the car, the axles were originally 28 spline. The 3:70's are a pretty good combination gear, but a little steep for freeway cruising.

mine also had 223 -6 .4:11 to1 big bearing 28 spline no o/d
I beleive Station wagons and Rancheros are all Big bearings. Just Got my hands on 9'' Rear end posi with 3.70 gears 28 spline. Im Running a 351 windsor mated to an AOD. I Should be got for the Highway.
sounds like my combo-351w AOD 3:55 to 1 Rellly works good -20mpg at 65. Step on the gas and She goes Wawwwwww!!!! :burnout:
I'm running a 351w/AOD with a 370 rear. I actually think it could maybe be a little steeper. Got to factor in your tire size when changing your gear. :smtree2:
