I did some research and in some ways this car is going to be easier and in some ways harder.
The decals for the 43 car are readily available online so I guess the main decal to worry about is the street decal. I am looking at some other race cars for inspiration as well.
There are 3 hoods to look at. A Road Runner with 2 wedges on the sides, an air grabber with a small rectangle in the middle and a bit of a bulge in it, and a flat hood used on the Satellite.
The plan is to avoid as many mistake as possible that were made on the Cyclone. For starters when I built the Cyclone I had no idea about what chassis might be available and loosely based it on hot glue and scavenged Carrera Doge Charger chassis. Later when Pioneer helped out with some chassis it was too late to alter the mold. The mounting posts were an afterthought and not at all a good solution.
This car is getting integrated posts that will allow a direct and secure connection to the Pioneer chassis.


This is a test print of the body to make sure the wheelbase and track are correct. I printed it up side down and chopped off the roof to save time and filament.

The same Carrera chassis will still fit with a bit of post tweaking. But who knows how soon we will be on ebay struggling to find one at a decent price?
Here is the CAD work done so far. The one spot that has me really worried is the area of vents in front of the windshield on the hoods. That is really tricky.

I ignored that on the Cyclone model because it was only introduced in 1971. 1970 hoods did not have vents there.
More later..................
