On my D 15 it froze but the frost plugs in the head did not pop out, does that mean it did not freeze hard enough,or is there another place I should look for either a break or another frost plug that I don't know about .there was frozen ice in oil pan.
 
No other frost plugs. Your block is probably split right down the middle and is now junk. Verify by removing the oil pan and seeing where the water leaks thru while you lay underneath watching.
 
The plugs weren't designed to pop out just because someone didn't have enough antifreeze protection. They are plugs that filled the holes that were used to cast the head. Sand was inside the head when the molten metal was poured and that's how they removed the sand when the metal cooled down. Anyway, if your radiator is low and the oil pan has a gallon or two of water in it, the block is split.
 
Where can one find the original oil gauge for the D series tractors I put one in from Farm and Fleet that showed the 70 pound pressure and a blue the
glass right out of that apparently you can only use the original or is there some other aftermarket replacement?

Engine oil pressure should only be 35 lbs. Maybe 50 psi max on a cold morning. The Traction Booster gauge is 3500 to 4000 psi.
 
To add to what Dr Allis stated the core plugs are not a freeze safety device as what calling them frost plugs suggest.
 
Which gauge did you replace and blow? As DrAllis said the traction booster system is in the 3500 to 4000 psi range. So the gauge and tubing are not just any off the shelf gauge and tubing for replacements. The store for this site sells both engine oil and traction booster gauges. Do an internet search for Allis Chalmers traction booster gauge and you can find several other sources as well.
