busted tach lens

[alee6x]

Hey all I busted a hole in my tach lens on a roll not sure how it happened but it did. Can anyone one tell me if it is removable or do I have to replace the tach
Thanks

It is not removable. I have one for sale on EBAY for $47 with free shipping. It is for edges with PERC reverse. They cost a fortune new.
