Do the servos sg90 and mg90s have the same shaft size?

I made pieces that fit on the shagt of the sg90 but i have to change it because I need more torque. And I don't have time to make new ones that fit in. Also I didn't buy de mg90s yet. Please help me it's for school and I only have one week. The project is done, I just need to solve this. Thanks very much

I don't know, but I suspect the shaft diameter will the almost identical but the splines on the shaft could be very different so that a servo arm that fits the plastic shaft may not fit on the metal shaft. The only way to be sure is to try it.
