Nylon Spur Gear for Spider Center Diff

Ok,
So, as we all know, Kyosho makes a nylon center diff spur gear, but it is a 4 hole, not a 6 hole, like the Ofna spider diff needs.
Due to my using a Novak HV4.5 motor for my conversion, I am under the impression that I need to undergear my buggy so I am going to use a 9T gear, but that gear is not so hard, and I would be replacing often with a new one.
So...
Via, a drill, a dremel and some JB weld I bring you....

I matched up the steel stock gear to the nylon gear, retained two of the original holes, I then drilled out 4 new holes, and covered the two old holes with JB weld.
Additionally I dremeled out the inside of the spur to match the stock (stock is sunken in, kyosho is slightly raised).
Then to account for the slack in the outdrive staft I put a brass washer between the bearing and the fatter part of the outdrive.
Because I drilled my own holes I have to go back several times and smooth out those holes so that I would get a good seal once the diff was filled with fluid. I also put some PTV silicone on the diff to replace the little orange o-ring gaskets.

I appologize for the shine on the diff in the picture, I hadn't cleaned all of the spilled diff fluid off at that time (10k wt diff fluid doesnt seem to like to come off to cleanly).

It has been sitting in my kitchen for almost a week and has not leaked, Hopefully my 0610i charger will show up today, and I can actually test everything out.
