TE Probe repairable?

I broke my TE probe at the fin socket. (Imagine cussing and dirt kicking)
After a bit more cussing, I managed to fish the broken end out of the fin
socket. (Of course, I did this AFTER assembling the Nimbus.)

The TE probe appears to have been a RU single function type with aluminum
two-hole tip, O-ring end that inserts into the 8mm fin socket and carbon
fiber tube between. The break was at one of the O-ring grooves. The probe
forward of the break is good. It seems possible that a new O-ring plug end
could be epoxied to the carbon tube.

Q's

Should I just buy a new probe?
Is there a source for the aluminum O-ring part to repair the broken probe?
Should I abandon the fin mounting altogether and consider converting to a
less vunerable fuselage probe over the wing?
