Allis chalmers plow

Looking for help to identify a my plow. I’ve looked everywhere trying to order new shares the one I pulled off had 5 bolt holes but only 4 bolt holes on the plow. It is 14” across the center of the frame. Any help would be nice thanks

It looks to be a 70 series from the Early 1960's
I Checked my manuals and it looks like the 73 Pictured on the bottom of my scan

There so many shares and moldboard designs by mfg.
There are numbers on the shares and the moldboard s that I’m sure you will need to find the replacements. First question anybody you contact will ask is what are the numbers on the share and moldboard s .
Additional information
I have an antique Allis Chalmers which I got parts from David Sousa of Spring Valley Wisconsin ,he is probably the best source of information on Allis Chalmers plows that I have found to date. He said he specializes in snap coupler plows .
Other excellent people resources
Watch the videos on you tube by John Garrd and Dylan Lynch
Also YT has Steve Smith from republic Ohio.
Plowox ,Salem ohio mfg. of plows shares and moldboard s

Best I can say abou5 this . Good hunting
 
The advice 560Dennis gave is spot on but with one caveat: The shares you take off might not be the correct and proper AC shares. Could be aftermarket will-fit shares and, as you stated, don't really fit as they should. The moldboards, however, are much more likely to be the originals and have traceable numbers.
 
If you want it for show then continue your search but if you just want a working plow get any 14 inch share and use your torch to blow holes in the right place.
 
Also noticed that the shins are 17” 3 holes and everywhere I look trying to get an idea what model number it could be no one has that shin on their websites either
 
I wouldn't stress about model numbers. The old plows were essentially the same across a number of years, and models. Especially when it came to the parts that actually met the ground.

Look for pictures that resemble your plow, then see what you have. Look at catalogues, and see if the pics match your iron.

Scroll down through the pics in this auction, and find the plow. It's representative of plows in those years made by/for AC.


There's a lot of this old junk out there (don't take this as an insult..........I run that old junk on a daily basis in a real operation). Find pics, then work from there. It's about the only resource you have. Purple Wave is a very good source.
