7-Bolt thrust bearing modifications

Does anyone know a shop in Ontario that has experience in machining a 96 7-bolt to accept 97.5-99 thrust washers?

I don't know specifically that he has done it but he is one of the best for custom machine work on engines of any type.

I like Gord, machined my head and block and allowed/helped me and a friend assemble the engine in his shop. Like an old encyclopedia that guy. Did amazingly well building my engine there but I had hookups

Rob, Did you figure this out? I am looking for the answer as well.
