Where is the lower part of the chain going to run? It looks like the pink parts are obstructing.

The pink part is a radiant style chain guard/cover and lower brace. It's hollow inside and the lower plate encloses the chain.

Correct. Here's a cross section view through the center of the guide:

Ah! Cool!

An update. I've had printed parts, and a donor Turbo Optima, sitting around for months. But, I've finally had some time over the holiday break to break the donor car down and do a trial assembly. It's coming along well and I've already seen a few things that can be improved. The chassis side pieces are 3D printed for now; I'll go with fiberglass, carbon fiber or aluminum for the final build. Or I may try printing a carbon fiber nylon. And I have a name for the car: The Turbo Pro Optiant .

Slowly getting there. Should be the final version of all the printed/fabricated parts...until I run it and something falls apart in the first minute .

Made some more progress today. Got the steering servo in, battery mounts installed and an additional chassis stiffener behind the spur gear. At this pace, I may actually get to test run it (sans body) this weekend!

Looks factory made! Well done

Love it ! any idea what style body your going to use ?

Agreed; this project is really turning out spectacular!

Thank you! I think the Kyosho designers would have done a better job, though. There are some inadequacies and more will show up when I drive it.

Thanks! I have an AYK Boost repro body from Sabula Tech. I originally wanted to use a Parma Desert Dog body, but it won't fit without extensive cutting.

That should look cool !
