Except for the earliest Radio shack drives (that were full height, stood on their side, and had the push button to disengage a disk), all Radio Shack drives supported 40 track (that first generation only supported 35).  If you have any of the newer ones (FD-500/501/502), then yours is 40 track. 
You are correct in that stock DECB only supported 35 tracks, and one sided. 3rd party DECB replacements (JDOS, ADOS, etc. )  could support more.
