I recently posted looking for a swivel seat mechanism.  Thanks to
this list I already have some leads but I haven't committed
yet.  Before doing so I would like some advise because I don't know
squat about doing this conversion (I can weld and use a
hacksaw).  When shopping for the mechanism out of other vans do I
need to be aware of the year of the van, or would they all fit with
about the same amount of effort?  Would one out of a '79 or '80 work
as well as something newer?  I have a 1990 Vanagon.

Thanks,
Andy
