For the THROTTLE PRESSURE LINKAGE (not kickdown linkage) on my 69 440 Charger, I modified a TV cable and lever off of a 5.2/5.9 Magnum. Works flawlessly, cost me $8, and a thousand times better than the stupid 3-piece garbage that came on these cars. Much cleaner too and can be adjusted in 10 seconds if need be
