The set over is now correct, though I need a few more passes to even out the pattern. When you reduce the set over, it cuts deeper in the back initially making a double pattern due to the springing of the necessarily thin boring bar. It evens out after a few passes at the same setting.

vtsteam:
Once the angle was right, I put the blued center into the original Craftsman tailstock ram, and scribed it where they met. Then I used that to test for the proper bore depth in the new ram. When boring passes allowed the center to  reach the same line, below, I knew I had bored to proper depth.

vtsteam:
Once the bore was finished, I needed to drill for the relieved section between the taper bore and the threaded back section of the tailstock ram. To re-center the steady rest, I loosened the steady's slot retaining screws, popped the MT2 center back into the tailstock and brought it up to the new ram bore. Applying a small amount of pressure with the handwheel centered the bore, and I tightened the steady rest down again.

vtsteam:
Then I relieved the mid-section of the ram with a 1/2" drill bit to leave 3/4" at the rear of the ram for threading to take the jackscrew.

vtsteam:
And here is what the business end of the ram looked like after finisheing the taper and midsection relief:
