Use U Brakes in place of roller cam brakes?

I have a 1985 Stumpjumper frame with the chainstay brake mounts, I believe this bike came with roller cam brakes, although I don't have those...I do have a set of U brakes from a bit later rockhopper...will these work? they slide over the stud mounts fine and they have an internal return spring where the bolt attaches the brake arms to the frame, I just cant seem to see how the springs actually work this way. Anyone done this conversion?

Bikes: too many bikes from 1967 10s (5x2)Frejus to a Sumitomo Ti/Chorus aluminum 10s (10x2), plus one non-susp mtn bike I use as my commuter

Many brakes have the return spring attached to a cam rather than directly to the base of the stud. Rotating the cam sets the spring tension, and when the mounting bolt is tightened it locks the cam in place.

Does that make sense looking at your brake?
