As Bubba described, he cut the factory 'end' off of the cable, and attached an extra piece of steel cable. You can buy the components for this type of stuff from a local sears hardware store, etc. You can make a loop with the new cable and hook it over the arm on the caliper. Slide the end of the cable into the crimp piece and crush it closed.

I believe J.stricker was able to keep the factory cable end and created a 'loop' from a chain link that the hooked over the arm on the caliper.

Both methods seem as though they would work just as well. The ebrake design isn't the same as the fiero where the harder/further you pull up the harder it clamps on the rotor. The 'vette ebrake only has a specified amount of movement and it stops, the 'tension' isn't quite the same. Basically all you need to do is make the cable so it can pull back on that arm.

I bought a set of ebay very cheap. If you can't get them there, others found them at Arts Corvette ( http://www.artscorvetteparts.com ), however they may run a few more bucks from there than on ebay. Push comes to shove, you gotta get em where ya can find em so if you have to pay a few bucks more, atleast you'll get the part. There may be other sources for them as well, just match the bracket to the same year caliper that you're using.

Just to add, I don't know what the difference is between the 85-87 adapter and the 88+ ones. They look to be exactly the same in every size shape and form, except the 85-87 ones say CORVETTE on them...
