2. My nav indicators are a King KI-204 with glideslope and an old

indicator and pushing in the new one.. will the pins match? Or is
this
something I just leave to the local avionics guy?

Are you planning on flying IFR with this aircraft? Do you REALLY
want to
slide down an "Ebay Glideslope" in the clag? Some things just cost
money,
man; let the avionics shop have a whack at this one.

In aviation, things are often counterintuitive. I've generally had
much better luck with buying stuff off ebay and installing it myself
rather than allowing an avionics shop to have a 'whack' at my airplane.

Unfortunately, the units are not pin compatible.

My advice - first swap the KX-170B's to make sure it's the indicator,
not the radio. Then, once you know it's the KI-201 or KX-170B, watch
Ebay for a good deal on whichever one you need. I find it's usually
more cost-effective to do that than repair an old piece of avionics,
and besides whenever the monkeys at the avionics shop work on a plane,
they break something. Better to do it yourself, and all it takes is an
A&P logbook entry. That's if anyone notices - you are, after all,
replacing identical parts...

3. If I replace the wing root seal, do I need an A&P signoff?
If you mean that black rubber thingy at the wing root, no. If you
mean some
sort of a speed fairing wing root seal, yes.

Actually, either one would be a non-structural fairing or cowling, so
either way no signoff needed.
