I"ve replaced the regulator and it is not that easy. The rivets has a steel core which make "just drilling them out" a bit difficult. If you have a decent drill and a set of cobalt bits you can do it. Drilling them out is the easy part. When you put the new regulator in place you must either re-rivet the thing in place or use a bolt with a nut. It is a very small space to put a bolt and nut on, a cherry max rivet would be ideal, if you have the equipment. Then there is the matter of aligning it so it works. This is done by putting it on, then testing, if you use a nut and bolt, it is just a matter of taking them out and repositioning the motor-if you riveted it then your drilling. I'm not saying it's impossible, it just not an easy job. There is more than meets the eye. I did it (which meens anybody can) but if I have to do it again I'm taking in to let somebody else deal with it. Hope this helps.
