Help identifing plow bottom model

I"m trying to find plow shares for my AC plow. I downloaded Gerald J"s parts books but I"m still having a tough time identifing what model bottoms I have. I"m hoping someone here can help.

I think I have a 80 series plow because it has the adjustable frame and spring trips. The spring trip are listed in the parts book as
"Stub beams and gusset plates (spring trip) 60 and 80 series plows, effective 1965" on p. 227

The plow is set for a 14" plow. The shares are 5-bolt shares The only part number I can find on the bottoms is 343854-2 on the landslide. These are listed on p. 136 on the bottoms part book as for a 370 series plow bottom or a 387 plow bottom.

The problem is that I can"t find any info on a 370 bottom and the picture of the 387 bottoms show only 4 bolt bottoms.

I"m also wondering if I have 16" bottoms set on a 14 frame. When I was plowing sod with it I noticed that on each pass one cut wouldn"t be quite rolled completely over like the other two.
But the starnge thing is that I have a 2nd 60 series 14" plow with what look like the very same size 5 bolt share.

If someone can help me identify what I have I"d very much appreciate it. Thanks!

I think what is meant by a 370 series bottom, there are I think 6 different bottoms in the 370 series. As close as I can tell, they should all use the same share.There are 5 hole shares made by an aftermarket manufactures, but they also say a 3 &/or 4 bolt will also work. Search plow share or e-mail me, for mgf. And yes, hopefully, those moldboards will work for 14 inch or a 16 inch setting.

I had a 3 bottom mounted plow on a D17 snapcoupler hitch. I don"t know what model it was but it had 16" bottoms. I would cut off a piece on the end of the share to create an anchor to help it turn over better in sod It never was a good plow especially if you had to plow a little up hill All the sod would stand on end. Needless to say, I traded it in for something green.
