Hmmm, i'm in the EXACT same boat as you, except with a 9" rear...and my safety inspection is due next month.
JMO, the simplest/most logical solution is LOKAR everything, from floor-mounted emergency brake($70), to complete cable assembly($79), from brake handle to rear brake shoes.
of course, hard-headed me, in order to keep the floor clear, is trying to locate either a 1997 Saab(swedish car) brake handle, or a chevy vega brake handle...onto the ledge, between the driver's door, and the seat.
for me, the original hand brake is not an option, because of the camaro subframe, and because every piece of the handbrake system was eliminated...just like yours.
FWIW, if i have too much difficulty installing the side-mounted brake handle and cables, i'll go for the tried-and-true LOKAR system...on the floor.
