[C38] Need PYI Flexible couplin model#

[Max Soto]

Hi Tom,

Thanks a lot for all the info. Now I know what to expect!
I thought that it was going to be easier!!! I do have a very tight space
between the packing and the coupling , so I hope it fits. I think that I can
have the flange locally made. Last year I pulled the transmission and rebuit
it. I took the flywheel  to be rebuilt because the rivets where gone. It is
working quite good, but if I ever have to replace it, the PYI is what I had
in mind.
Could you please send me some pics of your locker mods.
