Mike, I did that modification to the 199 on my 66 Rambler. I had the machine shop reduce the bolt diameter in accordance with the drawing in the service bulletin (and on Matt's site). I thought there would be less chance of stress risers if the machine shop did it rather than doing in at home on a bench grinder. You might want to consider this.
