My center seat holes:
Forward left hole- 11 7/8" from left wall.
Forward right hole- 19¾" from left hole.
Aft left hole- 6¾" from left wall.
Aft right hole- 30¼" from left hole.
Aft holes are 9" aft of forward holes.

My rear seat holes:
Forward left hole- 7¼" from left fender well.
Forward center hole- 19¾" from left hole.
Forward right hole- 13 7/8" from center hole.
Aft left hole- 2" from left fender well.
Aft right hole- 30¼" from left hole.
Aft holes are 9" aft of forward holes.

Note: the left 4 rear seat holes are the same spacing as the 4 center seat holes.

Even if the 55-59 seats will bolt up I'm also concerned with seat height. I now have a rear seat from I think a '60s burb in the center position and it is mounted on 2X12s to raise it.

I don't know how high the seats should be. Would someone measure that in a '47-54?
