See I missed out on first part of conversation . In looking at your pictures I went much further than that on my modified panel. I changed out all the old switches / circuit breakers with klaxton 2752 units .All the wire from wingtip to wingtip/ spinner to tail light lens with new Mil spec wire.I'd suggest a master cylinder overhaul kit(s) for brakes and new hoses. The airgizmo dock is good addition . the digital guages for engine parameters is good . See your still running a "T" control yoke ,I've got a "u or v " for anyone that wants one for sale. . Good time to add EZflap handle ,cargo net . extended baggage , firewall mounted battery , glare shield , more and more stuff .I'd like to your paperwork for the sling back seat. Thanks Bill Reid
