Long time archive reader, first time poster here.  After a couple years of having aircooled buses, I finally made to move to an 85 vanagon - heat :-).   I have an 81 westy that I was thinking of swapping the interior to the 85 (passenger).  I know the pop-up would be some work if I do it, but will the interior be pretty simple to swap?  I think I read somewhere that the 85 has a larger sliding door opening, but it doesn' t look like it would affect the fitting of the interior.  Any suggetions or thoughts of wisdom would be grateful.   

Thanks,

Mike
