71 Skylark, on the heater controls where you slide to the right for heat, is broken where it connects to the control. The cable looks to be frozen or hard to slide inside of the cable hence what caused it to break. Where can you find replacement parts?
Old Air Products. I bought cables for my '64 'lark. They are nearly identical to OEM, and very well constructed. http://www.oldairproducts.com/catalog/advanced_search_result.php?keywords=slider&x=0&y=0
