Anyone know the correct size shift **** for the threading on a Pro 5.0.....when I bought the car with the stock shifter, the previous owner put a t-handle hurst **** on it, but it had an adapter (assuming one thread was metric and this made it fit)....well the adapter broke and now the **** is too big to fit securly on my pro 5.0...any help? I'd like to get the same ****, so if someone knows the part # or anything I'd be most grateful
