Welcome to the club!!
I believe for a small flywheel, the starter required is with the two bolts inline and the outside bolt is shorter in length than the other.
It does not bolt to the bellhousing, so you don't have to fret about taking it off.
However, I do suggest the front starter bracket be bolted on as to help support it. I have seen the starters break, but, in rare cases. It bolts to one of the starter through bolts and to a bolt on the side of the block.
