has anybody tryed to put a 3rd seat in there wagen
i found one at local junk yard and was hopping to put in any body know any threads i can look at or any one have personl experience thanks

 

If the 850 is like the 700series, then all the mounting holes should be in the car fom the factory. you just need to take some notes/pics from where you took the seat from and install it in the reverse order you removed it.

 

...don't forget to get the seat belts too - the over the shoulder one that comes from the roof..etc. The bolt holes were already there on my 95 855 so it's pretty much plug and play.
