handbrake cable installation, how?

[hueyhoolihan]

i need to replace the part of the hand brake system that consists of the cable that runs from the left rear brake assembly to the right rear brake assembly. the rest of the hand brake system is working well.

my research, thus far, suggests that removal of the brake drum is necessary and that it is not trivial.

the present condition:

the car's (1941 ford convertible) had a recent (probably 10-15 years or less) body off restoration and the brakes, in general, work well. there's almost no rust on the undercarriage. the yoke holding the cable that needs replacing has been detached from the main single cable that runs forward to the hand lever in the cabin. the major wear on the old cable consists of significant fraying at the points where the cable enters the brake backing plates on both side. the rubber boots are, of course, in poor condition. the car had a new cable, still in it's plastic wrapping, in the trunk when i purchased it. i suspect it is the correct cable...

any suggestions?
