Yep, there are clean ones without holes (which is what I'd prefer in our case)
And a warning horn is required as GAHorn explained. However, the warning horn does not have to be mounted in the panel as no light is required, just the horn. On later (by '55) B models the horn (and light) are mounted behind the glove box deep in under the panel.
Great! We only have a small light in our current setup and would like to have a horn as well. The old horn looks neat and adds to the overall appearance in a classical panel, so we would probably have it visible. I've seen many have it behind the 1-1/4 holes (even though the horn is a bit bigger than that)

On my early ‘55, sn 26541, the stall horn and light are still under the left yoke shaft.

George,
As I compare the various Cessna 120/140/140A/170/170A/170B IPC's it seems that your "etc." actually covers quite a bit. I was surprised to see that even the stationary panel assembly on the 1952 C-170B shares a common part number with the C-140A. Here's a matrix showing IPC figure numbers for a variety of panel parts. Highlighted in yellow are parts that the C-140A has in common with the 1952 C-170B.
Henrik,
Cessna offers many of their Illustrated Parts Catalogs (IPC's) for free. You can find a link to them here. My suggestion would be to contact Sutton Aircraft Salvage and purchase the entire panel assembly including the stationary panel. For individual NOS parts contact Robert Brown. Here's his Facebook page.

Gary, this is great! Have been searching for such a comparison. Thank you very much! Did you compile yourself just now???

I've got the IPC already. Will check with the suggested companies! Thanks!

Yes, and you're welcome! It's interesting to see how many variations there are to those panel covers -- mostly differences in paint color, decals and/or hole cutouts for different instruments is my guess.
I forgot to mention that Ryan Smith has gone to a lot of work creating CAD files for the center shock-mounted panel. See his work here.
Good catch Jim. I should have referenced fig. 38-1 in the C170B catalog for the Stationary Panel. As in the C-140A IPC, it is p/n 0513110. In both the C-170B IPC and the C-140A IPC the entire stationary instrument panel assembly is p/n 0513111.
Jim,
I was surprised as well that the stationary panel was common to both the 140A and the 170A/B. I assumed that the 140A had a narrower cabin and thus had to have a narrower stationary instrument panel. In fact, the C-140A is narrower. Those clever Cessna engineers were able to use the same instrument panel on both models and make the C-170A/B wider than the C-140A by the addition of instrument panel support bulkheads on either side of the stationary instrument panel on the C-170 A/B. On the C-140A it appears the instrument panel rivets directly to the doorpost flange. So that gives the C-170 an additional 3-4" of width at that station.
Welll.. DANG! I sure missed up on this one! I kneejerked that answer based upon the 120s/140s I flew for hundreds of hours on pipeline patrol in the early 70s. We operated 120, 140, and 140A of various years and …(instead of pulling up 120/140 IPCs) …I had no recollection of ever seeing any panels that would fit the question, and of course the panels we just recently offered in the online auction were fresh in memory.
Thanks for the shock-therapy, Gary! (And GREAT WORK on that chart.)

Still no luck for me to find any info about the side panels. Some measurement would be highly appreciated! I guess the depth of the top and the side overlays is the same - is it about 1 inch?
As depicted from the IPC, you should be able to build the complete panel on a bench until you’re ready for the transplant. I like your approach and I think the community is looking forward to the progress reports.
