Side Mirror Plastic Cracked

Hi folks,
I have cracked only the black plastic inner portion of my truck's driver-side mirror. Mirror glass and housing is totally fine. Mirror works perfectly fine, electronics are totally ok. It's just the shitty plastic crack.
Anyone know how I can replace this plastic thing? Where can I buy it and how much will it cost? I'd rather replace it myself than get ripped off at the dealer.

Thanks.

 

Might have to replace the whole mirror assembly

Here is a part number for the assembly:
87940-04230

That assembly is for the SR-SR5 and includes the glass. There is no mirror cap because you already have one

Wow... That's a high price to pay for literally the shittiest, non-functional, cheapo plastic part on the mirror assembly. My fault for damaging it in the first place, obv...

So there's no chance of finding just the plastic piece? What's the best way to search for parts?

Thanks for the overall part number though! You rock.

 

You might be able to take it apart and glue it .

 

Check the junkyards

 

I’d take it apart and JB Weld it, file and sand it and call it a day.
