Does anyone know a fix for this in lieu of a replacement. Thanks

 

Replace it would be the probable choice. Q?...what color is the plug you have for it?

 

Plug is white with rain sensor

 

Dang, I have the one I had repaired as test for... https://www.radar-mirror.com/mirror_repair/ ...but it has the yellow connector. I'm quite sure they don't do frame repair. Yours is the same as the one in my VDP w/rain sensor.
But it may be best to go recycle yard hunting or go to a local British car show. Or you can try this, has worked for me in the past... https://car-part.com/ ...Carguts in Blacksburg SC has been a go to, very helpful...fast affordable shipping as well.
I did a quick check and a number of them are available site wide, the search engine will ask with or without rain sensor, but be sure to verify with the yard. Remember, these are scrap yards, their price isn't always the lowest price, you can barter.

 

Thanks for all the help
