Note that the hold-down clamp is angled to achieve perfect alignment with the throttle control arm when the throttle is closed. As the throttle is moved to full open, the cable deflects slightly.
Here is the bracket after trimming off all excess material and cutting a
lightening hole in the top, mounted to the engine with the carburetor:

Here is the other side showing the mixture control cable hold-down clamp:
The Carb Heat control box was mounted to the bottom of the carb. The
cable was run and clamped in place with an aluminum clamp as shown here:
Now to get the control cables into the cockpit and mounted to the instrument panel.
I had really thought about getting some of the fancy firewall pass through eyeballs and finally decided that I would simply drill holes exactly the same diameter as the cable casing and just slip the cable through the firewall. Once its all mounted and stable, I will seal the pass-through with some fire-sealant.
I really didn't have room on my instrument panel for the engine controls
so I made a bracket to hang under the panel. The bracket was made from
some 1/8" thick 1 1/2" x 1 1/2" aluminum angle. Here it is mounted
to the bottom flange of the instrument panel:
Starting from the left side and moving right, the controls will be Carburetor
Heat, Throttle, Mixture, Parking Brake. The parking brake has a "T"
handle so it can't be confused with the engine controls.
The spacing for these controls is 3" which works out nicely
The bracket is very sturdy as-is, but to add some additional rigidity, I
attached a couple of pieces of 1/2"x1/2" aluminum angle from the control
bracket to the firewall tubes:
The angles are attached to the firewall tubes with adel clamps.
Here is the control bracket with the throttle and mixture controls
installed:
I do have some concerns about interference with the control sticks at full forward and maximum aileron deflection. If needed, I will shorten the control sticks 1". I will wait to make that determination until I have the ailerons installed and I can see how far the control sticks move at maximum aileron deflection.
Cabin heat is provided via heat coming off the exaust pipes and routed into
the cabin through a cabin heat valve mount to the engine side of the
firewall. In keeping with my idea of keeping flames and smoke out of
the cockpit, I have elected to purchase an all stainless steel heater
valve:
There is a 2" hole in the firewall that the hot air passes through when the
above heater valve is in the "open" position. To help deflect the hot
air to both the passenger and the pilot, I made a simple piece of channel
out of aluminum and installed it over the 2" opening on the cabin side
of the firewall. The deflector was riveted on with stainless steel
pop rivets and will send hot air out both sides:
