So one plane under consideration has what I call a squirrely non standard six pack panel layout for the instruments. I want to fix this and install a third party STC panel from D'Shannon. How much would an A&P avionic shop charge me to do this work and how long would it take? Looking to find out from folks who went down this or a similar route. I am still a few years away from getting my A&P since I work and study part time on it.
