Dana 300 to Dana 20 Swap?

[cbmind]

Swapping transfer cases, the potential donor is a 60s Scout aristocrat with a Dana 20 and borg warner automatic. Currently have a Dana 300 behind a 727 automatic in my 80 traveler. Will the bull gear work that's in the bw in the 727 as well? I read somewhere the pitch of the gears is different or something, but can't find the info.thanks for the help.

The bull gear (spicer p/n 18 8 56) pitch angle on the 727 is 17.5* with a spline count of 23.

The bull gear (spicer p/n 18 8 31) pitch angle on the bw 11 is 20* with a spline count of 6.

I have one of each in front of me now.

Sounds like I need a different donor
