Has anyone ever fitted a Delta unifence to a Rigid 4512 Table saw, if so, how difficult was it?

Cast iron drills easily so drilling a hole or two shouldn’t cause you any major issues.

I put a Biesemeyer Commercial fence on mine. was not hard to do at all.
I’m not sure how different the Delta fence is, but syenefarmer is right. drill the cast iron to match the rail where you can.
The stock fence on the ridgid saw uses nuts and bolts on the front rail, and the cast iron is tapped on the rear side, and has no room for a nut. So direct threaded bolts only.
I had two holes line up perfect on the front, and drilled the cast iron to match the holes on the rail.
On the rear rail I had to drill the rail to match the pre tapped holes that came with the saw. And I was able to use the bolts that came with the saw for that.
I also did a cast iron wing upgrade at the same time, so again I just drilled the cast iron wing to match the holes in the rails.
The big thing to watch out for when drill the cast iron is that you miss the ribs.
Photo is of the rear rail showing the bolts I used that came with the saw.

good luck

Don’t know how familiar you are with a unifence (great fence!) but it has no rear rail. The t-square head rides on the front rail and a foot that glides on the saw top and extension wings. Therefore, the wings need to be flat on top, not dished out or open-grate style. I’m not familiar with your saw, but the pics on Home Depot appear to show the wings are flat on top.

If the width of your saw table, with wings, is less than the unifence rail length, then the table width will limit how far you can slide the fence side-side. I can’t tell what the extension wings are made of, or how sturdy they might be for attaching additional extensions to match the unifence rail length. You may want to keep the existing rear rail just to support the extensions between the existing rear rail, and the unifence front rail.
