How about aftermarket getting side mirrors with blinkers?

 

I seen a lot on ebay, as long as you don't have turning signals you are lucky. Worse case cenario buy one in any color and have it painted. Paint shouldn't run more then 50-100 bucks. Good luck and let us know how it goes. Btw someone stealing a GS side mirror is a low life crackhead scumbag. Sorry for you're loss.
