M35A2 Cylinder Liners - Type "Y"

[martinv]

I have found multiple sources for type "Z" cylinder liners, but my Continental LDT 456-1D has the "Y" stamps.
Though a Z fits, I don't know if it will work as it is slightly smaller OD.
Are the "Y" types extinct?

Where is it marked?

Where is it marked?

from the TM:
"
1. Look at left side of crankcase opposite each cylinder bore about one
inch below top of crankcase. The letter "Y" opposite a cylinder bore means
this is a Y-size cylinder bore. The letter "Z" opposite a cylinder bore means
this is a Z-size cylinder bore."

In the picture below, you can see head is off and one cylinder top is visible. The stamp is circled in yellow:

Ah Ha! The marking is on the block itself, not the cylinder liner! A long time ago a number of people got lots (usually of 9 if I recall) of them at a GL auction of LDS piston sets (piston, sleeve and oiler), but I did not think any of them had a mark to indicate the size. People who have rebuilt that part of their engines will have to speak up.
