I restored a Ferguson plow with cast points and no tail wheel.
1. I had a John Deere modern "rock share". It is of the radix design, with a curved down point and 4 bolt holes, with 2 bolt holes close together at the short frontne torch to cut 2 holes thru the existing cast points, using the new 2 holes as a template. I then bolted the new radix point on. Now if I ever wear the JD point out, and if I can still purchase a JD "rock share" I will just have to make a new cut one on. Normally a point wears more at the front of the point and less at the rear. In the 1940-50, We used to have a blacksmith weld on a car spring to the worn out point, to refurbish it.
2. Since I needed to replace the worn out front/short landslide, .I used the remaining part of the JD rockshare, as the replacement, again using the old landslide, as a template, burn the 2 bolt holes.
3 For the long outside worn out landslide, I welded a worn out Ford radix point on the existing landslide.
4. I welded another 6"length of of a worn out point to the other point to gain 6"of permanent landslide to replace the lost tail wheel.

Lots of labor, but doing my own its free.

I now have a $400 + plow, that should last my lifetime, or 20 acres,, whatever comes first.

I know this post is old but any pictures?

A few years ago I was in my "plow mode" scouring ebay & craigslist daily looking for all things Dearborn or Ferguson plow. Complete assemblies, partial assemblies, various parts. Back then you could actually find shares once in awhile, sometimes listed wrong, or in a small lot of various parts. It seemed like the supply all dried up since then.

Good job rebuilding your own!
