Thanks to all who responded on the moving the front rotating seats from a
westy to a weekender.  I'm not sure where I got the idea that this was just
a unbolt and bolt in swap, but I am disapointed that it's not :(.  Anyway, I
am thinking I will go ahead and do the passenger side conversion.  It looks
like there are 6 welds on each side that hold the base to the "original"
seat tracks in the van.  Are there other welds underneath that I will have
to deal with?  Anybody tried a Dremel with cut-off wheels on these?  I can
see going through a lot of wheels, but it might be worth it.
