It took a darn long time to 4x measure the correct length and winnow vendors. See attached. The cable is treaded from rear of the instrument panel, a U-turn to run alongside the pilot side of the aircraft, and throught the firewall just left of the fuel. 3 new clickbond studs were added to further secure the shielded, armored throttle cable. At the engine end the armored throttle cable goes into a steel tube with external threads, then a small dimeter smooth steel tube, from which emerges the moving 10-32 threaded solid rod. To the end of that threaded rod is an engine-rated clevis with a 3/16ths pin, matching the hole in the throttle arm. I modified of piece of aluminum angle so that it bolts (two 1/4-20 by 3/4" high strength bolts, with split washers) to the existing tapped holes in the oil sump. That bracket holds two engine compartment - rated Adel clamps. The forward one is secured around the steel tube with external threads. The one further rear is secured around the small dimeter smooth steel tube. There was a fair amount of measuring and re-measuring, which meant 1st try success in cutting and drilling the bracket. There is full throw of the throttle are with no conflict with any structure throughout the travel.
