Not sure if it's the same for 84 as for 86, but the cable on mine comes off the e-brake handle, runs to just in front of the rear axle, splits, and each part goes to one wheel. Then there's a small loop at the end of the cable which is hooked over an L-shaped bar with a hinge at the middle of the L. Cable is not normally fastened to the bar with anything but tension, and they must come off occasionally because the previous owner of mine had them welded together on one side. The other end, IIRC, is attached to a spring that pulls the brake shoe against the drum. The bar itself is bolted to either the hub or something around there. It's been almost two years since I looked at it; I can dig some pictures up if you'd like. What specifically is the problem?
