Marcos Maniacs

I have an 1982, #8001 Marcos with the Capri rear axle (the gears 
unload from the rear).  How does the rear handbrake work?  Does it use 
the Capri, relay lever, rear pulley (on top of left axle tube), and 
transverse cable, like the capri did?  My car has a "tab/bracket" 
welded on top of the left hand axle tube as per the build 
instructions, but that bracket is not shown in the Capri workshop 
manual.  I assume the handbrake works on both rear brakes?  So does 
Marcos use their own handbrake assembly?  The cable that goes from the 
floor mounted lever to the handbrake assembly (how ever it works), is 
that cable Marcos specific?  My car is left hand drive.  The Marcos 
build manual states; the cable fits to the compensating mechanism of 
the rear axle".  What is the "compensating device"?  Is there enough 
room between the relay lever and panhard bar, if the car uses the 
Capri handbrake assembly?  All my car has, is 
a cable from the handbrake and the bracket on the axle.
