Do you know if it would bolt to a turbo 350? I have posted this question previously and have not gotten any response. Also, what condition is it in (useable, destroyed, or needs a rebuild) and apprx amount of miles?
 
I pulled it off of a 700R4 in working order. The most I used it was one trip home (apporox 200 miles in 2wd) and pulling 1200 # hay bails around the yard in 4wd once I got it home for a few months.

To fit it on a TH350 you will have to find or make an adapter. The 700R4 adapters won't work for you.
 
Do you know why it would not work? The only thing I can think of is 700s and 350s might have different tailshaft lengths. I believe they have the same spline count, and sae 4 bolt trans mount, and sae 6 bolt round on the transfer case.
 
The difference is in the length of the output shaft. The TH350 only sticks out about an inch past the rear bolt flange while the 700R4 sticks out more like 5-6". So if you use a 700R4 adapter it will all bolt on but the TH350 output shaft and tcase input shaft won't actually touch.
