Not to worry. Art Morrison chassis, Chevy performance parts LS and trans, 50 state legal. Nine inch ford or Corvette IRS. Yes that would get us going. What they have in them in Cuba is not relevant.
I know exactly what’s available for them. I own a ‘55 model 210. You forgot to mention Danchuk and C.A.R.S. inc. And Goodwrench crate motors.
