Misty, since no roadster fellow builder comes to your aide, here are some pics of how I fitted the handbrake cable to the chassis, but I must mention that my chassis is a McSorley 442E and not a roadster, but should give you some pointers.
The fuel tank is mounted above the diff away from the rear panel for safety sake and you can see how I routed the cable to rear hubs.
Btw, my car has a raised opening bootlid
(level with top of roll bar bases) and thus may seems strange on pics without it
