I now have the complete couplers and shafts for both transmissions.
These transmissions are over $1300 new + shipping. Both of these are freshened and like new. Save yourself some money!

I have 2 Winters Falcon transmissions. Both have just been freshened with clutches, bearings and seals. In excellent condition. Ready to go. One is complete with coupler (2 pc rear seal crank) and intermediate shaft. $850 for that one. 2nd one has coupler (no intermediate shaft). Left upper ear was broken about 3 yrs ago. It was repaired properly (see pics) and has been used since then with no problems. $650 Will ship at buyers expense.
