I started doing interior swap at October. First I removed old seats and put them into winter 940, its old front seats had seen the best days.
Mk1/850 seats needed two new holes per seat to make them fit to 940 rails. Heaters are not hooked yet.
I bought a set of 2004 S60 seats at summer, and set of 240 tan interior pieces from Finnish Volvo community member. Donor car was a SE version with electric windows and mirrors, so I got them to my car also. While interior was out, I clened up some electical mess that I had under dash etc. I started to put tan pieces in. That wiring stuff took a while and I lost my interest to do any car related stuff.
After two to three months of playing drums and moving stupid amount of snow I realized that I got to do something or car ain't driveable at spring. I painted dash lower section and assembled S60 seats to 240 rails
Seatframe is luckily quite same as p80 related cars. I made few adjustments to buschings and seats are now at better positions. Drivers seat is now dead center of the steering wheel.
Next job, and that what I am currently doing was rear seat. The place where you put your butt had to be shorten by 70mm or ~3inches and it was a bit too wide around wheel wells. Back rest fits when S60 mounting brackets are cut out. It's a tight fit but it is unnecessary to cut it.
Next job is to make proper attachments and upholster wheel wells.
Nice job
Plan b was to fit gauges where radio is at, but I am more than happy that I was able to put radio there.
