I bought one of those gears about a year ago. I installed it in my '39 regulator with good results. I ended up drilling out the rivets which serve as the pivot points for the two arms of the regulator, then drilled out the rivets which holds the replacement gear to the arms. I used aluminum aircraft rivets (1/8" dia) to install the new gear onto regulator the arm. I then used .250" dia. bolts and nuts with small bushings on them to replace the original pivot point rivets. If I remember correctly, the shoulder on the original rivet is about .280" diameter. You could probably just drill the holes up to .312" dia. and use 5/16 bolts as well. I had to use a small file to re-work a couple of teeth on the new gear as it would bind a liitle bit. Not a big deal. Works very smoothly now.
