Brake Roller Track Rivets

Thanks for the response. I have already tig’d my tabs and just need to mill them flat. I used to have Les’s book but no longer. He has surely helped the hobby a lot but I sense there are some areas where I’d be better off following my OCD by choosing the factory drawings over his instructions. No offense to him as I’m sure his way is better than leaving them damaged and is surely more attainable than machining. However, indexing off of bucked rivet heads doesn’t sound too precise when I will be using a mill. I like benchwork but I doubt I could file that accurately. I guess I’m wondering if indicating off two of the backing plate mounting holes would be precise enough to establish parallelism of the tabs for milling. Distance from the center of the axle hole is easy enough.
I’m sure filing would get me close but just so I can relax and hope for self-centering, I am planning to replicate the factory drawing tolerances.
