Of course! This is solution for emergency.

Sounds like great and very practical advice - thank you! Will talk to my A&P.

Certainly with you there... I do have second VOR - legacy Narco 122 Nav.

Bull's eye! I'm one of those g IFR flyers, with just a few months of IFR rating... :-) Thank you for advice!

With you there! That's why I got GFC500... And even then I did weigh $$ vs benefit. Benefit is tremendous, and I'm glad I did it. There's no comparison to how I flew w/ my old S-Tec 40 and now. On the other hand - radio or GPS failure in my mind leads to immediate need of getting out of IMC as quickly as possible, and having ability to talk to tower or CTAF to land. Having secondary COM/GPS is very convenient in THAT EVENT, but does not really provide as high a guarantee as dual magnetos do for continued flight, for instance. Electrical failure risk remains, and it feels to me (perhaps incorrectly) it is likelier scenario than failures as seemingly narrow as radio/GPS (b/c alternator is mech device I guess?)... If I could have purely emergency cover for both that is also inexpensive - I would just continue enjoying failure free so far flying w/o large expense. Hence my hesitation. It is obvious, however, that options eval does continue in my mind! ;-) Itching to spend =)

How much $$ is it reasonable to continue pouring into over 60-year old plane? ;-) After GFC500 upgrade, which I find invaluable, I'm in the territory where 100% of further improvement expense is unrecoverable, vs typical 50%... Stacking that against the reason you gave is my challenge.

Got IFR just 3 months ago, but am already flying a good mix VFR/IFR...

My relatively updated panel (GTN650, GFC500, dual G5s, GTX345) has only one comm/nav provided by GTN. I had outdated second comm before getting my GFC AP, and did not want to spend $$ on moving it around, thinking I'd rather get something nicer later. Now, after flying like this for a year, I'm hesitant spending any more $$. Feel comfy as is, and carry handheld as a backup (which will have to do in any event in case of power failure). Any thoughts on what would justify another bundle of greens on 2nd comm?

Thanks! Sounds like best answer...

This set https://www.knots2u.net/hub-cap-w-access-door-6-wheel-set-of-two-lsm-200-701-1/ looks great, but how does one get around the issue of nipples hard pressed against wheel bearing cover? So far - I couldn't check tire pressure or inflate wo removing wheel cover AND bearing cover. With that - these will not help? Or did you have different experience/figured something out?

http://www.dallascustomsteeringwheel.com/ Radio button I found @wingsandwheels.com Momentary PTT switch for $9, but I don't see it on their site anymore...

Just for everyone to see my final result - here's how my yokes now look.

Looks great! Thx for posting.

Anyone interested: here's what I got (and this is where I got it: https://wingsandwheels.com/momentary-ptt-switch.html). I had to grind bottom part to fit into the hole from old vacuum switch

Anyone who used this M20C original yoke and installed PTT in place of the old PC button - what's the diameter and depth of that hole? Need that to figure which PTT will fit in it ...
