Armory414,
'Don't know about the tang on your 63, but the tang screws on the 62 look to be correct for the (Win.) Lyman No. 2 tang sight. That sight is meant for the 94, but fit right on my Winder, which I compared (with dial calipers) to the Taurus. Perhaps all Winchesters had the same angle and screw spacing, and Taurus reproduced it that way? I got that sight from Cabelas. They've gone up to $80 now! :eek:
