What can be said about the 4-speed New Process NV833 overdrive manual transmission?

[Gregski]

I did search the forum but could not find anything relevant.

So word on the street is the 1980-85 two wheel drive trucks may have had the 4-speed New Process NV833 overdrive manual transmission. (this being a popular Mopar transmission)

1st = 3.09
2nd = 1.67
3rd = 1.00
4th = 0.73

I currently have the 4-speed Muncie SM465 manual transmission, which only has 3 gears, the Low being useless for me and my driving needs. So it's just a practical 3 speed with a 1.00:1 tallest gear.

First Gear - 6.55:1
Second Gear - 3.58:1
Third Gear - 1.70:1
Fourth Gear - 1.00:1
Reverse - 6.09:1

Have any of you done the swap, how difficult is it? Can I use my old bellhousing?
