TD340 Hydro seal question

Morning all! Merry Christmas,
I finally got the little guy running again. I now have a hydraulic question.
In the left side of TD340 is the hydro pump. On the outside of that cast housing is where the hydro pressure line is located. Bolted to the housing is another housing to which a hydro hose is mounted to that feeds the hydraulic distro box. Between this housing and the pump housing there should be something that seals that area. It is either an O-ring or a flat ring. See the pictures to understand what I am referencing. Where can I get this ring. I have no ring, it most likely fell off during the first disassembly.

Any good parts store or go to Harbor Freight get you a 9 dollar O ring assortment if they have one in the box big enough or measure across the milled part in the first photo e mail me an address and one will be in the mail tomorrow.
 
That O/Ring is suppose to be the thin one . same as used on the 340 on up thru the 560 farm tractors . In my service truck i have three styles of O/Rings in kits i got from my nut and bolt supplier . they Fat ones ya get at harbor freight or the farm stores are to fat ya want the Cat thin ones . Or just go to a Case I H dealer and get the one for the 340 tractor . From the engine back to the trans everything is the same on the wheel tractor or crawler.
