…I think Juha Airio was involved in creating the master. That was about 20+ years ago.
I think R&R Vacumcraft(?) had a standard 1970 Chrysler 300 in their catalog for some time.
Now, there are several 3D prints of both the standard and Hurst ‘70 300’s available.
I think if any of the model companies decide to tool up a big Mopar C body, the 300 and Hurst 300 would be a great first choice.
