Hey all,
After months of searching we found a 1955 170B and bought it back in November. Great plane - love this thing!
I’m trying to do minor improvements , but keep it as original as possible. I’m going to add a usb charge port - bought the stratus port. Want to mount it below the panel and incorporate the rheostats for glare shield lighting.
Here is a picture of what I’m starting with. These brackets are riveted on, so assuming original? What’s the big one sticking out used for? Hand mic maybe? Don’t have a hand mic.
Looking for ideas to clean things up and install under panel.
Thoughts? If you have pics of your install, that would be great.
Thanks,
Scott
Is this bracket original and what’s it for??

Re: Is this bracket original and what’s it for??
Short answer: Yes, that is a microphone bracket. p/n 0713203-1.
Long answer: On the hidden portion of the bracket is there a female receptacle for a microphone jack as shown here? The very first major alteration (337) form for your plane is for the addition of radios. It was outfitted with "Selection #6 Narco Super Homer VHT-2" and "Selection #8 Narco receiver" by Ralph Bevan Radio Company in Wichita on July 19, 1955 -- shortly after leaving the factory I presume. Without seeing this 337 form for your plane I mistakenly assumed your plane would have originally had General Electric radios because of the number stamped on that bracket. It looks like 2055. I think this is a G.E. number because the '48 IPC lists the part pictured in fig. 48-15 (General Electric Radio Installation) as 205S and, in the numerical index as 2055. Four digit part numbers are not typical for Cessna-produced parts. For later models (post s/n 18573) my guess is that Cessna bought this part from G.E. and gave it their own part number -- 0713203-1 -- which you can see in several of the stationary panel drawings shown in the IPC.

If you need to replace that “lost” GE…. The Assocn has one for a small donation.

Ok, thanks for the info. Behind that mic bracket is now 2 circuit breakers- COM 1 & COM 2. No hookup for mic.
I’d like to remove that bracket and the bracket with the rheostats to the right of it (both riveted on) and make a new bracket to hold a pull switch for glare shield lights, usb charging port, and current rheostats. (you can see the rigged setup to the right of rheostats for on/off toggle (toss that switch)
I’m guessing I could mount the new bracket under instrument panel to the right of flap handle swing - like the circuit breakers in front of pilot.
Thoughts on where I want to put it? Anyone have pics of this addition on their plane? Spruce only has one type of pull switch - any pull switches on the market that look similar to the original ones in the plane?
Thnx
