Drilling and taping the crank for a damper bolt is best done by a engine builder or machine shop. With the 59 235 engine and the short water pump I experienced some clearance problems with the stock fan blade as it comes around hitting the new damper bolt. One thing leads to another and in my case finally went with an electric fan in front of the rad. All a damper bolt provides ispeace of mind.
