Well, it can happen for sure. While all three gears are mechanically interconnected. Tube assemblies can get damaged and bent, perhaps due to miss ringing the gear system and side loading during the landing. IIRC, Bravo at KSFF had a left tube assy bent that way and it failed, perhaps bent at previous landing(s) as the pilot reported landing as normal, then the LHS leg just collapsed. BTW, it took a year to completely repair the plane. Crazy!

Maybe @tomgo2 can help you with one. Good luck.

What's up with 6 pilot holes for the fasteners and zero edge margin on a couple of them. That's is where you'll have a crack in the future.

It's been a while but i believe C172SP is fuel injected (IO360) and has eclectic boost pump....

That's pretty much how I remember it too. I never flew behind one but this article on Falco builder website is quite informative: http://www.seqair.com/FalcoBuilderLtrs/BldrLtr0388.pdf

I have a few covers for sale here: Some are dished, Cleveland parts and one is probably home made, being flat.

It's hard to say but RHS panel took longer due to complete rewiring and adding new circuit breakers above the original ones. LHS panel install took probably one full weekend once the cutting and powder coating was done (Seattle powder coating). This requires some downtime in order to remove the old panel and figure out the proper layout and to assure the clearance to the structure under panel. I've done the LHS panel while waiting for the engine from the factory. I chose the off white shown as I prefer light colors and contrast provided with instruments. I used dry transfer lettering and clearcoat on RHS panel which looks great. LHS panel done later was with some self adhesive foil that you can print on and stick on the panel but I wouldn't recement them. Make shore that mounting holes are properly located and clearance holes so you can position panels correctly. At that time I used a LASAR kit for installing the flat panel. Heather did some research and provided standoffs/spacers (see below) and Lord rubber mounts for the panel. Price was less then $50.0 but some of the spacers didn't have a adequate length to place the panel to the angle required for the turn coordinator so I purchased few at McMaster Carr. I think even rubber mounts can purchased there... Some rewiring was needed as instruments have Nulite underneath the panel. Those were wired to the original pot at the ceiling and worked quite well. CAD work and selecting hardware and such was easy for me but I design airplanes for living. it shouldn't be that difficult providing you have an access to CAD software but perhaps it's the best to get the panel from a pro and install it yourself. One thing to be aware, original secondary structure needed some moderate trimming to clear the ASI al the way at left top corner. If you look at the first picture posted by 47U, it will be self-explanatory. Good luck.

I'm sure it was done on a number occasions as I remember reading about. Anyway, attached are pictures for LHS and RHS panel. Unfortunately, I don't have final CAD files I created as I used a (former) work computer.

Few years ago I used company in ATL area that is now part of Xiometry. I created the CAD file of the LHS and RHS panel and used their online quote process, selected Al Alloy (7050 or 2024) and got the waterjets parts. If I recall correctly, it was about $300 per panel. https://www.xometry.com/ Please check their website for current details and quite process. I recall the old company (Big blue saw) had a web based CAD software you could use but I never did try that since I use CATIA for work. I did the install myself with the IA oversight. Good luck.
