The limited availability and price of the original replacement parts forced me to think of another fix, so I looked at mounting a traxxas VXL tranny. I already had a Integy aluminum Traxxas gear case so I used that as it's more compact then the plastic original. I also had some other parts for this swap kicking around, so I wan't out much more money then it would have cost to replace the original Tamiya parts, and replacing any future broken parts will be a lot cheaper and easier to find.
I want to get another set of A-arms as I fudged these ones up a bit, I didn't get the holes drilled for the rear carriers just right which resulted in too much toe-in, but it's a cheap & easy fix.
Here's where I'm at with it now.
