Welcome on board, Angela!
I am super sure, that your refit project will have a big reward and you will get et least 500% back.
Just have a look at Skipper999 here in the Clubhouse. He provided great PS43 videos on Youtube and I was in contact with him via PM (personal message in the forum). He might be of great help with some of your renovation challenges.
In addition, that's why I did create this forum, please be encouraged to ask questions in the technical section, as many details of the Pilot Saloon are the same across the range. So we all can take profit of that knowledge.
Please be encouraged to share pictures of your renovation here in the Forum.
As hint, Philipp did also renew his rigg (I think) in France. Later he did a refit in Turkey:

You might me able to read his blog with Google translate. Philipp is also active here in the Forum and you should be able to get him via mail or personal message.
Have great progress with your refit!
