<VV> Late model brake adjuster hole

[John Miller]

I seem to run across a lot of late model drums with the brake adjuster hole punched out. This has not been a problem because I had a supply of metal adjuster hole plugs,  which I recently exhausted. As you all may well know rubber plugs dont last long (melt)and the water gets in....never that fun. Anyone know where a supply of these metal plugs might be found? The place I used to get then locally went out of business.
