Welp in this case, the newer seats are out of a 2000ish (?) m-b c-class.
Had them for another project that didn't happen so this worked out.
There is NO welding required. I drilled out the factory feet off of the toyota (year?) buckets that I had in there that earlier replaced the toyota factory bench seat; enlarged existing holes in the feet brackets & drilled out small rivets in front of those holes & made same size as the enlarged holes.
The rear brackets take one carriage bolt each (bolted pointing down); the immediate second (slightly enlarged) hole goes over the mercedes metal dowel on bottom of m-b seat rail.
The front toyota brackets (feet) use two carriage bolts each, pointed down they clear inside the m-b rails.
The beauty of this is that, going into a originally-bench cab, once the feet are properly positioned/bolted to the m-b rails the toyota brackets (feet) can then be lined up EXACTLY with the existing toyota factory threaded (outside rail) floorpan holes.
I manually offset/adjusted the inner m-b rail slightly to accomodate the hole previously made for the old toyota buckets so that the rear foot lined up with the hole. The seats are electric (relays next) & forward/rearward slide adjustment is manual so shouldn't be a problem.
The seats are way more supportive & comfortable than the old & tired toyota ones.
Did I say there is NO welding required
Due to the front inside feet having lower under-side profile than the outer feet, the bolts & nuts required some grinding to not high-center the bottom of the brackets (feet).
More pics with notes later.
