"I got one of these from the guy who originally invented then down at the antioch outpost. You'll need a set of calipers to use this correctly.

Line up the holes, loosen the screws on the 1shot until the snugly press against the gearbox, separate the gearbox shell and measure the total height of the screw and 1shot for each post.

Then measure the height of your gears not including the part that goes into the bushing / bearing.

Subtract the gear height from the 1shot height and thats how much shimming needs to be done.

Saves a lot of trial and error if youre trying to get that perfect shim height
