Bridgeport CNC

[tpmx57]

I was thinking of converting my Bridgeport series II over to servo motors using this kit from Keling
: 3 PCS KL34-180-90 (NEMA 34) Dual Shaft, 1125 oz-in Peak
90V/40A
I am concerned about the torgue of these motors compared to the original steppers and also the mounting difference between Nema 42 and Nema 34I also believe the original steppers are running a 2-1 reduction.
I would prefer to use my original pulleys and belts.
Anyone been down this road?

that's about the torque i have on my series I ,it's on the low end of torque but it cuts fine with the j2 2hp spindle .5 dia. end mill
