I've done this on my 90GL.  Search the archives for info. but basically you
get a swivel seat base that's been cut out of a westy, then either drill and
bolt it into your van, or better yet get it welded in place.  Your seat
slides in with no problem.  I think any year swivel seat base will work, the
main thing is to make sure it was cut out of the donor vehicle nicely.

Hello out there

I have a 1990 multivan and want to make the passenger seat swivel to face
the rear of the van. Where can purchase a swivel base and what year swivel
base will suit my purpose.
How do I attach the base ?
Does anyone out there have a base for sale, e-me with cost and condition and
any other info on doing this.
