400a autopilot to Century Non-slaved HSI

[rmorris]

UPDATE:
He went ahead and put in the old DG, so it's still wired to the Navomatic 400...but since he tells me there is a bad servo, he didn't hook-up the KLN90B or KX155 to the ap (ie nav inputs).

So I'm looking at two options:
1) Source a servo for the Navomatic 400 and ask him to complete the install - which still means that I have to have my old DG for heading input, not my newly installed Century HSI
2) Find a cost effective upgrade to the Navomatic 400 instead of just replacing the servo on thois one.

All comments welcome (either here or email me at rmorris@agsi.us)

Specifically -- sources for #1? suggestions (and please keep the 'go buy a new STEC 60' to yourself, looking for other alternatives that come from experienced owners/pilots/mechanics)...maybe a way to upgrade to a newer Navomatic with minimal part changes and labor? Of course, sources for any parts suggested for #2 as well.

Thanks,
Robert
