How do I do this? It strikes me that I need...
some side windows some rear seats a new back body with 2nd-row doors a new back door (?)
How tricky is this to do in practice? The doors strike me as the complication - what do they hang from and are there any hidden problems with changing the back body?
I guess it would be possible to retain it as a two-door, but that makes it a lot less useable for what I have in mind.
