I drove a street car with a converted full manual VB (Chrysler instructions, separator plate, transfer plate) in 1970.
Hated it - got pulled over many times for smoking the tires on the 1-2 shift with light throttle. Couldn't drive it on wet pavement unless the steering wheel was centered or it would loop on the shift.
Same problem with my DD now (dangerous when wet), except it retains full auto upshift and kick-down.
