After market seal kits for Kubota cylinders?

Best if you post them here, give other folks a chance too. Someday if I finish the 10 high priority projects my wife has me working on at the same time I'll take a shot at 3D printing.

I've attached a zip file with the actual FreeCad file. The three parts, "slide", "pusher", "correcting" are all in the one file and a print file, usually an STL file (in my limited experience) can be produced for each one individually. It is a FCstd file specifically for FreeCad but may be readable and usable in other CAD programs.

I've also included a screen shot of the "spreadsheet" that allows each piece to be custom sized by changing the values. That feature might not be compatible with other CAD programs.

I've also attached a copy of the WSM page the describes the parts and usage, even though that may be obvious to some. This is specific to the B21 backhoe (BT751) but should be adaptable to most.

I knew there must be an ulterior motive.

You figured me out. Yeah, I gotta run over to Texarkana and get some parts. Oh don't worry, I'll be fine. Sure is a long way to go but I'm pretty sure I'll make it. No you don't have to go, I'm just running over there and back...

So, looking for reliable after market sources for compatible seal kits.

I realize this is an old post but I wanted to encourage folks who end up on this thread to buy hydraulic seals from a local shop that rebuilds on-site.

The boom cylinder on my BT600 backhoe (BX23D) started leaking recently. The rebuild kit bag with a Kubota label was $102 + shipping + tax. I took mine apart and brought the end cap and piston with seals to the local shop. I asked for all the seals x2 because one of the other cylinders is sure to start leaking eventually. 10 minutes later, I had my bag of seals. $73 all in for two kits.

I was unable to put that seal in my Kubota cylinder. I ended up taking the gland back to the hydraulic shop that I bought the seal from. I expected they had a tool to do it but he did it by hand in 5 seconds.

I just did one today, method I used before.
I fit a short socket in the bore, rachet side up.
I push against that to get the seals rolled up like the tool would do. Needle nose, roll up, push down to flat.
Follow with another socket, push all through to slot, fix small bit hanging out.
