For all my old (junk), out dated machinery, I just pull the seals out (look on youtube for how to's) and take the old seals to Napa, they can order anything you need. They got me seals for my Brantly backhoe and loader. They also got me seals for gear boxes and all kinds of other old out dated stuff.
You could probably find some online too, just make sure you measure right!
You could also go to a dealer (like cat, case, bobcat ect) and they could probably get you the right seals or tell you were to get it rebuilt at.
Good luck!
