...help me here. When you speak of gear sets your are talking about what....ring and pinion?
I'm curious as I use to get special gears made from a local shop (Griffin Gear) for the company I helped manage and while the cost was not cheap I was surprised several times at the quotes. They made many gears for us. Excellent quality and been in business for years.
I go down that way ever now and again and would just like to drop in and see the guys and maybe, just maybe get a ball park figure to see just how staggering it is?!
...there I go, thinking again.
