Very cool. It'll be a while before I can afford something like this, but it is awesome you came up with it. I'm sure it is well worth the wait.
Just curious on weight compared to an old one? I have the 23 spline in my car and could care less if I have to change to 18 spline. It just plain makes sense to use the 18 spline. I'm sure his investment costs are already high, so maybe if these sell well he will switch, but once again, why settle for second best.
Can't wait to Wonder if I'll bust my knuckles w/ my bench seat
