How big is the hole in back of a bellhousing for an NP420? Or what is the diameter of the front bearing retainer on a 420?

I have Clark 207VO 5 spd overdrive that I want to sell. I have evaluated how I could mount it in an early Power Wagon. One thing it requires is a collar around the front bearing retainer so that it pilots correctly into the bigger hole in the Dodge Bellhousing.

The early Power Wagon has a hole approximately 4.75" The Clark bearing retainer is smaller at 4.175" I'm wondering if it would be a better fit on a 420 bellhousing?
