Wexco 4R1.12.R110D 1.5" Wiper Motor, 12V

What is the on center measurement between drive shaft & mounting hole at back end of motor?

Will this bolt up to a curtis cab mounted on a jd x748?

I was on another site and they said this part number would work. but i don't see my number (wwf12c18-210) listed in the cross reference chart above?

What is the proper orientation, motor high with transmission hanging down. Or motor low with transmission sticking up? For wiper to park left
