Explanation on starter question.
The $149 price is a complete starter including shipping. That is the starter motor with a 2 inch diameter rubber wheel, a manufactured nose piece and two mounting legs welded onto the starter housing.
If you have your own starter motor and want to build the nose piece assembly yourself, the nose piece parts kit is available for $30 plus shipping.
In the attached pictures note that the rubber wheel is
NOT included in the nose piece parts kit but is available separately from Fixture Works part # RR-2020-80-EX750 cost $24.45 plus shipping. Also, the bronze bushing which is in the kit, is not shown in the picture.
We hope to get a picture of the complete starter itself on this blog soon. (currently having photo troubles)
Lastly, please know that the actual nose piece parts kit will be different from the pictures due to the fact that those were made from scrap metal and was the R&D unit.
