Third Update - I went back to Kubota (Did Not Go Well). I was informed that, based on my units serial number, neither the inner or outer boots were available and I would have to buy a new axle assembly. At which time I expressed my opinion and I don't think they will want me coming back to their facility.
Not being one that quits, I did my own research. I took the old boots and measured them, search for "CV Boot Size Chart". I found a site in Europe that gave me a ton of information which I took to NAPA. The clerk was able to find both boots which will be here in 2 days for a total of $55 for both. If it works out, I will post the part numbers.
