I'm pretty sure the two on the VersaBlock go all the way through and mount on the transmission plate, but are those other two bolts on the sides meant to mount the gearbox to the channel as well? It would seem like they are, because there seems to be a hole drilled on the outside for Hex key access to the bolt, but at the same time I don't see how the bolt would get into the inside of the tubing.

All of your other answers totally answered my questions, thanks!

Also, I'd love to see the CAD if you could send me that, Thanks - I too use SolidWorks.
