My Ford stamp has arrived.

I want to remove the oval, but fear my eyesight is not good enough to do cleanly.
A jeweller friend will shave it for me if I want him to.
Any tips on rebuilding the 11" Ford pressure plate assembly? New one is only $40USD, but another $70 or more to send. I dont believe mine is bad. I just want to examine all the pieces closely, before I feel it can be trusted enough to go into the engine.
I'm part way through a voyage of discovery with regards to oil flow in the French Flathead block. Because those engines were designed to run a governor and hour/rev meter, there are some openings above oil pump which I will be blocking off. On the weekend I will insert my borescope into the oil passages and compare the French block against an original Ford offering. Internally should be identical, so am just double checking route for the oil lines to & from external filter
