I got this from a business closing..This is new and in the factory box..It looks like the rebuild kit is here too.I didn't look up the part number on that, but you can.There is also some mounting bolts and instruction papers.The thread diameter measures 1-7/8" .The box is dirty from sitting on a shelf for a while, but it's all here and perfect..I will be able to ship in a USPS medium box (that's the plan), and you will see it in a couple days.
