Huh? NO. There are no spacers concerned with the mounting of the bracket. Just mount the new bracket straight to the old one. As far as I know, all 47-54 MC brackets are the very same. If you bolt it right up, it will be 3/4 of an inch to far to the passenger side. There are NO spacers. The only single spacer is to re-align the plunger. No spacers in the mounting at all.
So, even if they look different, those years everything was spaced the same. So, bolt directly to the old MC bracket. Notice how its too far to the passenger side. By about 3/4 of an inch. Right? Once you are there, its easy to fix that 3/4 with a spacer ON the plunger system. Its how CPP does it.
