well I've been trying to figure out why my alternator has been Slightly misaligned. Finally found the culprit. The mounting hole is "wallered" out causing it to tilt in when you tension the belt on. Hopefully this will help someone else.

Any suggestions on a quick fix, extremely hard to find this bracket for a 1964 Chrysler 300k 413 WITH AC.

What about the threads in the corresponding hole in the front of the cyl head? That much "angularity" might have affected it, too, possibly?

That bracket looks similar to the one on my 318 poly 65 Polara. If you can't find a replacement, clean it up and get out the oxy acetylene torch and bronze rod and braze the worn spot up and die grinder/rat tail file to fit.

If you aren't a stickler for originality, perhaps the later style stamped steel bracket assembly would work? You might need to use a Denso alternator for clearance tho because I think that cast bracket mounts the alternator higher on the engine, at least on my Poly it does.

Thanks for all the input guys. I think I'm going to drill out the hole slightly bigger, where its then even and add a metal sleeve/shim.

Probably the easiest route

Might try this, great idea Kevin!
 
So Kevin, I guess essentially, id buy the rods and use a bernzomatic torch and just melt the rod in the uneven part of the hole, filling it in?

If the Bernzomatic can get it hot enough, yes. It needs to be heated bright red hot which might be a stretch for that Bernzomatic unless it is the 2 tank setup. Otherwise you might have to pay someone with an oxy/acetylene torch to do it for you.

A talented blacksmith can weld in a plug, which one could tap.
It might be beneficial to find someone who has said talents.

This YouTube video points to such a solution:
 
I do believe this is the pivot mounting for the alternator. This should be a separate bracket, (hard to tell by your picture).
If this is, all you need to do is open the hole, and install a sleeve large enough for the pivot bolt to go through

The only problem with enlarging the hole is that if you drill it out, the drill will follow the hole. Since it's worn to one side and probably not straight anymore, the new hole won't be straight and won't be centered either.

The proper way to do this is have someone strap it down to a milling machine and actually bore it to the correct size for the new bushing.

Might just machine the front side down enough that a thicker washer will be flush with the normal mounting surface. Then secure the washer and tack it onto the casting. Touich-up with a grinder to ensure a flat mounting surface with correct height and alignment of the bolt hole on the bracket.

Just some possibilities,

Good point.

Just this morning, I was told by the mechanic that did the required NYS inspection on my 300 that I was actually told that I was the most normal Mopar guy he knows.
You must have had on your Tool & Diemaker hat. That's what fooled 'im. :rofl:
