All Hail the King of Stovebolts - King Tommy!!!!Your memory is only slightly foggy. Once I saw your description of the air compressor as "radial" - and I googled that - I found the link below. And on page 1A-5 - in figure 4 it shows the exact bracket I have been turning every which way for a couple of days. As you can clearly see (and me too) there are two bolt holes in the front of the block that accommodate one mounting bracket - and two bolt holes on the side of the cylinder head for the other bracket. Then - the one you are a little foggy on - is a bolt hole under the fuel pump on the side of the block - instead of on the motor mount.

An Octoberfest toast to you. Long live the King!
