Prob like 6-9k+ if your going to pay someone. Depending if your talking about seats too etc could apply the +. So many countless little things to get working to make it all work properly just electronically. Not to mention even if the panels dont have to be cut, bondo, painted to fit you will have to drill new mounting points, friction clip attachments, wiring harnesses. There are probably few people that would be willing/able to do it for you.
If you were to spend months hunting pick-a-parts, ebay, and craigslist for all used parts, and then were to do all the labor yourself your looking at a lottt less. But probably a year long project if you have a full time job
I know its sentimental to you but if its sentimental just put it in a garage and then put that 5-7k towards a new one
If it was me I wouldn't mess with it no matter what the sentimental attachment but thats just because If something is sentimental to me I'd personally like to leave it in the form which gave me those memories
