Another interesting source of body shells. Entz Racing Components on ebay. Many euro and American including a 1969 Corvair like my 1967 real car. Require full scratch building of car since only the body shell is 3d printed.
I need dashboard gauges for my Mustang and only found 1/32 fighter plane decals. Are those the good thing for car interiors, or is there a real car gouge source I missed?
And so we have the 3d chassis conundrum where there is room for wide tires like we use on the modern big track. I vote 6mm unless 8mm looks period correct. Just the direction I am taking.
