Dear Frank, Thank you for the information. I like to let you know that the transmission on my car is 4-speed and I like to know which one of the ratios (3.69:1 & 3.92:1) would match both the engine and the gearbox. Furthermore, I need to have the part number of the differential suitable for my car.

See revision above.

Dear Frank, would you recommend using a 5-speed gearbox with a differential with 3.92:1 ratio and what would be the result?
Thank you in advance.
