Hi all, i have a 2000 Focus SE witg the SPI and 217k miles. It has the IB5 in it, but i have no 5th gear. The day before yesterday, i took off the end case, while the trans is still on the car, and noticed that i cannot even catch a fingernail in the gear to spin 5th gear. I called a local auto wrecker, and they have an IB5 in stock, but it has iptions for 3 different model numbers. Will ANY IB5 bolt up, and work with my 2000, or do I have to have a scpecific model number to work with my 2000? Thanks in advance.
