10 bolt rear may be a couple inches wider ( and I think the ujoint is some sort of 3R which may require a 1310 to 3R ujoint (inside clip). Not a biggy. The 12 bolt will accept a 1310 most likely like the driveshaft now.

I do have a 9.5 14 bolt 3.73 (5 on 5 lug -- now 6 lug) with G80 in my 67 but they are not that easy to come by. I had to use a 1310 to 1350 ujoint on it.

I too do not like setting up or paying $500 for new ring and pinion and install kit and someone who knows what they are doing for labor. X2 for front and rear.

I now am dealing with a 10 bolt front and rear for a 4wd project on a 59 GMC. I will have to watch the offset in the wheels I use. I want tires under the fenders.

Easiest for rear would be a 12 bolt with usable gearing.

Greenwood is not that far from Cincinnati US74.
