gmbuffallo, there are floaters, and then there are floaters. Depends on what car you have as to the type of floater. Flathead Ted sells what he calls a floater, but that's for the '32-'34, and I'm not familiar with that one. The '37-'38 floater is a star wheel, adjusted by a brake spoon. The star is on a shaft threaded left one side and right the other. This replaces the original wedge, which was intended to float, but in fact only floated enough to provide erratic braking action.
The original shoe return springs were a set of 4 color coded springs of different values. The bottom 2 are still used with floaters, but the top 2 are replaced with a single 91A spring, connecting shoe to shoe rather than shoe to backing plate.
After installation of the star floater, you're left with an empty adjuster nut hole on the backing plate, into which you reinstall the original adjuster after it is cut free of the wedge. (It is of hardened steel, so you need to use a cut-off wheel.) On the Concourse then, your floaters are undetectable by the Judges.
A final note here on quality of the part: The floaters I used required a bit of tweaking in order to not bind up on itself as the shaft turned within the threaded portions, as they had been manufactured slightly off center, producing a wobble in use. I found mine at a swap meet years ago, yours may not have this problem.
