Good to see a lot of discussion on this. I used a regular Torx, not a Torz Plus, T-40 on a 3/8’s socket that I was able to borrow from my former work site, an airport maintenance shop. I was just a helper with the mowing crew as a summer retirement job, not a mechanic. Thanks again for all the help over the years.
Thanks for reporting back about that Dan.
TwinTurbo, that explanation actually makes sense to me - some combination between expiring patents, organizational interest, and engineering and all. I’ll have to remember that I really do like to buy tools. You know - it’s that love/hate relationship with getting new tools. I will eventually need to have a set handy.
