You might want to call or email MGW with a couple of questions. They're good at responding. Ask if the shifter you ordered has the same threads as the stock one, and if not, what threads will it have. If you got a flat stick it'll definitely be different. Also ask if they think a 15 oz. knob is a good idea; their answer might surprise you.It came with the car. It weighs 15 oz. I’m hoping it will work with my MGW I just ordered because I like it.
