Ka-6 TE Probe

My Ka-6 currently has no TE compensation for the Vario. At one time it
had a Scheumann compensator installed, but this nifty box didn't come
with the glider. So now I am looking to install a TE probe.

Does anyone have any recent experience in installing one?

I was initially thinking about the tail mounted type (probably the
ILEC with the socket), but the fuselage mount type would be a much
simpler install. Is the tail mounted probe worth the extra effort in
install over the fuselage type?

Does anyone have a Schuemann compensator gathering dust they want to
sell?

thanks
