They way we are describing the gear ratio and shaft number is just lame. The gear boxes are not say 4:1. The motor gear turns way more times around for one complete turn of the drive sprocket. Probably 50 or maybe even 100 to 1 is the real gear ratios we are looking at.

I would like some higher ratio boxes than the mato steel bearing ones I have, also brass would be nice but guess they are gone.
The mato boxes screw into the mato hull from the top down, so the screw heads have to be accessible from the top through the box.
Will the taigen sherman gear boxes allow for screws to be inserted from the top... ok that's a dumb question because it all depends on where the screws go.

I know the Tamiya boxes have super tight clearance between the gears and the bottom plate so don't think they will work for top down screws. But really it seems like I will just have to get gear boxes sent to me and see if I can drill new holes in the bottom in the places I need to insert screws.
Talk about trial and error.

Really though, I would recommend against the MAto steel gear ball bearing boxes due to the total crap that they miss in QC. I should have sent that bad one back but didn't know it was bad until now.
