simplicity sunstar engine question

I have sunstar that I am repowering with a 18hp briggs. I do not have the original 18hp kohler and I need to know the distance from the center of the crank to the base of the engine. If it possible for someone to measure from the center of the elect clutch on the front to the base of the engine it would be greatly appreciated.
Thank you

Well I finally go the Briggs running not to may mods deff lighter but a bit taller and the exhaust barley fits in the hood. I may have to check on muffler options if I want to use my headlights other than that prob cost a total of $2,500. I used all new u-joints, pump seal, pump filter/fluid, a new nuckle on the pump, sent the drive shaft in to have it shortened and make sure it was straight, new fuel line, and some basic nuts n bolts. Price seems high to most but I priced out a couple diff tractors with a blower and a deck and they were over 6k.
