It depends on how you exit. University Avenue southbound is 124. University Avenue northbound is 72C, before mainline eastbound 80 joins.

But usually, if there's an exit number for the route with it's mileage, that should take priority.

Oh, and weirdly enough:

87 -> 137(80) https://goo.gl/maps/SW4y1Pa473C2D45E9

Exit numbering at the northeast mixmaster is stupid and I have no idea why. I-35 should have retained its mileage number, and I-235 should have Exit 14. But they're ALL signed with I-80's number, so Exit 137A refers to EB 235 from WB/EB 80, but also EB 80 from 35 and 235.

Also, if I change the University exit to 72C, does that mean the west mixmaster (80/235) needs to be 72A instead of just 72?
