I bought mine from "HydraPak Seals, Inc" out of Utah. They struggled a little with the O-rings as they specialize in regular hydraulic cylinder seals but they seemed to work fine. The three rings you are interested in are the following:
1.) Cylinder cover o-ring which is a "G55". I didn't take my cover off as I worked from the rod end so I didn't need this. HydraPak P/N 054.40X3.10-N70
2.) Main piston o-ring is a "P50A" - HydraPak P/N 049.60X5.70-N70
3.) Backup ring is a "P50A backup ring" - HydraPak P/N MBT-49X3X1.25. These are Teflon and do not have a split so you have to cut one with scissors so you can get it over the piston crown and into the groove. You'll need two of these to make the same thickness as the original from what I have seen. General recommendation is you cut the slit at and angle kind of how you do wood baseboard seems. Not sure how much better this is but I'll continue to do it this way until I see a reason not to. Keep the seams 180 degrees apart when installing.
I'm guessing most o-ring suppliers can get these, I just happened to pick HydraPak. I had good experience with their regular cylinder seals also and their pricing seems reasonable.
