Motor Cage for an HK UMP (CA/G&G)

[GODSPEED|seven]

So I have an Classic Army UMC (same as any other HK UMP on the market).

I purchased this AEG brand new, and after 500 rounds started having motor issues, and after about 2500 rounds the motor cage became slightly defective;

The motor height adjustment screw stopped adjusting the motor height. Whenever I tried to adjust it, the screw would just come back down to the lowest position; I checked the screw, and the threads look fine.. I'm guessing the threads of the motor cage are busted. I've had this problem for about 1 year now, I simply put a spacer, and the motor height is "ok".

There are a few things I want to fine tune in my gearbox (see my other thread: http://www.airsoftcanada.com/showthread.php?t=129923), so I thought it would be good to fix any issues first, this being the only issue I have.

My question is;

WHERE can I find motor cages? (spcifically for a Version 3 gearbox .. UMP style)

I've looked at ALL the online stores I know (from canada, to USA to worldwide) and they all have gearboxes, but no one sells motor cages!!???
