I found ones from Spec.R that look like they would work but didn't want to drop another $37 just to see if they would.
Not the answer you want to hear but drop the aluminum knuckles and keep the Tamiya axles as they are the best (most durable) IMO. Seen too many problems with aftermarket axles that I will only run the Tamiya pieces. If you must run the aluminum knuckles then clearance them with a Dremel to work with the stock Tamiya axles and you will likely not have any axle reliability issues.
