I was just looking at the doing what you suggested but I will have to make the length adjustment at the lever end. The end of the shaft at the far end has a pined yolk connected to the clamp riser mechanism. There is a two inch long 0.5" diameter shaft that has a threaded hole that screws on to the end of the rod and this two inch long shaft has a 0.62" diameter shoulder/flat blade screw head on the near side end of the fence. The actual rod ends about 1.5 inches inside the end of the casting around which the aluminum fence is fitted.

What stopped me at first is if this is a 24-1/4" deep table and the table saw table this fence was made for is 27 inches, then the distance from the far side rail to inside of the hook at the far end should be close to 2.75", but it measures 2.54". What I mentioned earlier about change one thing change everything implies an understanding of the entire system, and I obviously am a long way from being there. I guess taking it apart and sketching and measuring every part of it is next. There is a double action to the lever that pushes a brake against the near rail as it pulls the rod that sets the brake on the far end. No way to thread it though for a trial fit, but that would be nice.

So now I have to try to understand this thing enough to determine what size the pieces should be, cut them and see if I am right. What bothers me is my most basic assumption is not backed up by the measurement. This has gotcha written all over it.

If I go only by what I see, I should just cut 2.54" off the rod and aluminum channel, drill a couple of new holes to mount the casting and see what happens. Or does what I measured make sense because Delta table saw tables are really only 26-3/4" deep?

I have a 1968 PM66 that is 28" deep (new aquisition, came as part of an auction to get a 6x48 Delta belt sander) and a Craftsman Professional (made by Jet I believe and had forever) and it is 27" deep, so I am betting the Delta is really 27" on the dot, but confirmation and (if possible) a measurement of the fence (just to confirm same/similar parts) would be nice.

I have read the only difference between the fence Rockwell/Delta sold with the table saw and the fence they sold with the band saw was the length, same casting and mechanism, which is why I bought this fence. When I bought the band saw from Southwest Texas Medical Center in Dallas, it already had the rails on it. So if someone out there has an original Delta/Rockwell fence steel or aluminum for any 20" Delta band saw with a 24-1/4" deep table, could you take a couple of measurements of your fence, that could be very helpful?

Will take apart and post pictures tomorrow.
