I don't post much, more reading than anything else BUT, I bought a 1987 IROC, the cable that hooks up to the bracket to control the temp was missing. Had to replace the heater core and thought that I could repair the problem when I had it all apart, no such luck. This is a daily driver and don't really want to take it all apart again. Tried to make a bracket to hook the cable to, again, no such luck.
Any Idea's

 

broke down and ordered heater box
