The back rail is only to support the extension table that the fence
will rest on.

The back rail has absolutely no function to support the wings on a PM
66; they're precision-milled castings bolted to the main table...

When mine was manufactured (still in McMinnville, TN), they were still
being surface-ground at the factory in place before being removed again
for shipping...they quit that later to control some of the costs, but
they're still milled flat w/ square, true edges to mate the main table
casting.

I don't know what they're now shipping for fence options; the "classic"
66 had just a couple of 5/16" bolts with a formed nylon washer to fit
the round shape that bolted through oversized holes on the table to let
it be (the rail) adjusted to the table, not to help support the table
wings at all...

Understood but if you have or add the 50+" rip capacity the fence needs
a side extension that will be approximately 8~10" wider than 50". IIRC
most saws will have side extensions but not that far out from the blade.
