Hi, I had the same problem and did not get a clear answer from anyone. But, i have another stepspeed car and the dip stick length from tip to the underside of the stop flange is 427mm. good luck with your replacement one, I repaired mine with a jubilee clip. AllanIn my 2000 MGF, the transmission dipstick has broken. I need to know the correct length for this dipstick so I can modify another to fit?
