Darick,
Your set up for your controls is identical to mine. I have had no problem with this placement and everything is very intuitive when you are flying.
I also have the Vernier control for the mixture. I believe this allows the engine to be run at peak smoothness and efficiency. I had the button lock control earlier, but the Vernier allows much more precise mixture control.
For the terminating end of the wire on the mixture control check out this :
https://www.aircraftspruce.com/catalog/appages/wiregrip.php"WIRE GRIP - Is a unique fitting which securely attaches to solid wire end push-pull cables. Uses a "pin vice" gripping action to attach a cable. The 5/8" long 10-32 threaded end will attach a clevis, ball joint, or other hardware for use with mixture controls, carb heat box, cabin air, or other applications, resulting in a clean, professional installation."
for use with this AN665 THREADED CLEVIS TIE ROD TERMINAL assembly:

Great looking work on your plane!
