I had one made for my 216 by Buffalo Enterprises. Took awhile to get, but the quality is seemingly high. I went with a 3/8" grove for my '52 216 so modern belts/accessories can be used. A 3/8" belt simplifies using an alternator and adding an a/c compressor. The '53 216 water pump uses a 3/8" belts, so that part of the equation is easy. All this is moot point for the 235, I think, but might be handy for others stumbling on this post.
I will probably only use one of the two grooves, but I now have a spare in the event it is needed in the future.
BTW, I also drilled and tapped the crank snout to able to bolt the balancer in place as well as draw into place instead of beating it into place.
