Just my opinion here - if you have the time and space to pull the interior before painting, I would absolutely do it.
There are so many nights I sit here fiddling around in the garage wishing I could take this entire car apart, and put it back together like new.
Everything I do, I say “I wish I could get that done, or I wish I could get this done”. But I need more space, or it will become one of those clusterphks people end up selling. I refuse to go that route.
I think your pretty into the details, from what I’ve seen you do, so if you can manage to get that car apart, repaint, and then put back together, that’s what I would do.
