Stock Turn Signal Mount Mod
In first photo I used belt sander to sand it down
In second photo I used a dremel and cut off wheel to remove some plastic
As can see it fit spot on
There few more steps you need some tape to cover the hole
Then get a can Oatey ABS Black Medium Bodied Solvent Cement, 4 Oz #30999
Some 180 grit sand paper to rough up the surface
Cleans the surface with acetone
Put some ABS glue in there cover half up the hole
It will take some time to dry a few days then you clean it up and paint
