I got my pump back and the tooth / gap spacing is all the same. What I did see is a mark on the front of one tooth and I found a mark on the collar of the gear that was over a gap which I assumed were my timing marks and they were. I took a red marker and marked the entire top of the tooth and the mark on the gear so when I got the pump in (which is very tight to do) I could see they were aligned. I blead the air and it is running great again. Here are pics of the marks.My local Kubota dealer was not much help. I was able to locate expansion plugs that are 34.925mm and they worked great. Napa has steel 381-3080 or brass 381-9008. Pump is not back from being rebuilt so was easy access. (hope this helps someone else)
