Wow,
That is one interesting setup..
Yes, the 10-spline input gear is made to Marlin's specifications by Toyota's actual gear cutter in Japan, or in other words, our gears are made using the most current and state of the art machines!
I would have to contact Marlin so it will have to wait until Sunday or so..
Yes, it can be purchased seperatly, no problems at all. And again, I will have to get back to you with a price.
Regards,
