1990 308D - Merc seat swap - Johnnn

Hello, new here, just got a new-to-me 308D van 1990.

There are, ahem, a few jobs which need doing but one of the first is sorting out the seats. Who the hell needs bucket seats in a van?!

My plan is to swap the passenger seat for a 2 person bench.

Questions: (awaiting my manual in the post)

1. I presume it's a straight swap - unbolt old seat and attach new?

2. Do newer seats have the same bolt pattern?

Thanks in advance.
