I removed the carpet from our stairs and there are two treads that are
split. I don't have access to the bottom due to a plaster ceiling
underneath. The treads are high on the flight so both ends of the tread are
encapsulated in a dado in the stringer. I'd like to remove and replace the
treads.

Getting the old tread out will be messy but quite possible. I figure to
plunge cut into the middle with either a circular saw or a Fien with the
right blade. My question is how to get the new tread installed?

Any suggestions? I have a full woodworking shop, so very little is not
possible. I've just never worked on a stair case with both sides
encapsulated into the stringers before.

Here is a picture of the left and right sides of the stair tread.

Show us the damage--my inclination would be as others to repair it
instead as first choice. Unless it's really bad, a glue joint may be
almost indistinguishable and as strong or stronger than the original
wood. (Done lots of antebellum renovations in VA; seen about as bad as
can get, salvaged most...)
