Wow! I didn't know it was that expensive. Glad I went the route I did. Can't remember on the length of the stock adapter between the th350 and the np205. I wanna say it was the same. With that advanced adapters kit you'd want a 2wd 4l80e. Preferably 94 or newer. If you got an older one you'd have to switch out the internal wiring harness. Not a big deal really.
Here's what their site says:

The adapter assembly fits 1971-79 GM NP205 with a figure 8 front bolt pattern, and is designed to replace the 10 or 27 spline male inputs. If the GM NP205 is equipped with a 32 spline female input, the new 32 spline input that is included in the kit will not be needed. Call our tech line for more info.

The adapter kit is designed for exclusive use with the GM 2WD 4L80E. The 2WD 4L80E must have a 6-1/2” slip yoke output shaft. A GM 2WD 4L80E output shaft speed sensor must be used"
