parts compatibility between 850 and 940/960?

[urbex]

Just blew the bottom end in my 850 this morning on the way to work, and looking at all options now one of which is to dump the 850 and move into a 960 (or perhaps a 940 assuming a good enough deal). Main reason for going RWD is that I want a chassis to do a big power project some time in the future (somewhere around 500HP), and it will keep me in the Volvo reliability for the time being.

That said, if I were find a 940/960 with some issues, are any of the parts from an 850 compatible with the 940/960 cars? Obviously most of the drivetrain is different, but what about accessories or interior stuff? The leather in my 850 is still in great shape, and if I could swap that into a 940/960, I might be able to save some money on a car with a rough interior. Are the dashboard/consoles similar enough to be swapped without major fab work?
