I checked the discs one saids 29 the other saids 69 over a 12,which I would guess means 12/29/69.The tranny came out of a 1970 montero.It looks like It was rebuild or at least serviced in the past and the guy I bought it from said it ran perfect,it was on a 351.The torque converter end of the input shaft is 26 spline, we won't know what the other end is without pulling it apart ,not that it really matters at this point. What kit would you guys suggest or other mods based on this info. Thanks for your help, Mike Sr
