key, in the "search" header look for top creep or cable adjustment. Cable adjustments are done with 4 bolts on the street side, near the tires. I can't guarantee your '85 model, but as you look at the bolt pattern, the top bolt on the left adjusts the right front, lower left adjusts the left front. Top bolt on the right adjusts the right rear, and, of course the lower right adjusts the left rear. Adjusting requires 2-- 9/16" wrenches and a vise grip pliers. Vise grips (or the proper wrench) is used to hold the back-side of the bolt from spinning (the proper wrench requires a third hand, I don't have one of those). Use the 9/16" wrenches to separate the nuts (locking nuts or JAM nuts). Then 1 wrench is used to tighten (to RAISE) or loosen (to LOWER) that corner. I do this when the top is down to put a little slack in the cable, when I've taken a turn or two, I run up the top to see where I'm at, and continue from there. Takes a bit of time but worth the effort. Any questions, just ask.
