I only welded from the top, it's basically sheetmetal, so either you got it
welded together or you didn't.  So I don't think welding from the bottom is
necessary.  I think the floor would crack even if the seat was firmly
attached.  The backs of the seat rails take most of the weight, and they
have a square end which is right at the end of the bolt.  To make matters
worse, the nut holders are spot welded to the floor, and have square corners
in about the same place as the seat rail.  This seems like a recipe for
fatigue cracks.  Once they start in thin metal, they are likely to just keep
tearing due to the seat rails pressing down on the floor.

I did wind up getting some 1/8 x 2 bar stock and running it from the square
cross member in front to the rear wall.  This should help spread out the
force and keep the back of the seat rail from punching through again.  I'd
have liked to tie the seats into the frame, but not until I can get it up on
a lift.

Good luck

Chuck,
 I noticed your e-mail and checked later, to see if anyone replied. I didn't
see any response, but I have a question for you.
 My '73 had a very loose drivers seat. When I removed the seat, I noticed
the left front mount, to the base, was very loose. The bolt had been
replaced with a smaller diameter and longer one. After removing the base and
carpet, I discovered cracked metal, from the nut to the door sill and about
5" along the door sill. You say you welded the floor, I was unsure if I
should have the cracks welded from the top only, much easier, or top and
bottom.
 I think if the seat didn't wobble, the floor wouldn't crack.
 I didn't have rust around the nut area, but a little along the door sill
area.
Larry
