This is a new, very popular and long-since discontinued Downey adapter kit that mates a 23-spline top shifting gear drive mini-truck transfer case behind a GM Turbo-Hydramatic 350 3-speed automatic transmission.
The required transfer case will be a 1979-1995 4cyl gear drive t/case converted to either a 1979-83 or 1985-88 EFI top-shift style with a 1986-87 23-spline Turbo Input Gear, available separately here.
Never been installed. We have two kits available
