Greetings fellow ACD members. We are proud new members and new owners of a 1931 Auburn 898A cabriolet. Our intentions are to prepare and rally the car in The Great Race 2019. As many of you will know this is a time / average speed event usually over 2,000+ miles. I expect we will have our work cut out to sort the car and appreciate all the help we can get. It would be wonderful to know if anybody has any history on the car, it's likely it went through a complete body off quality restoration some years ago (perhaps over 20 years according to our inspection report) and has not been used much since. The VIN is 89830622F and engine looks to be GU59014. I'm sure we'll have many questions as we bring this glory back to life. Respectfully, Colin and Bob.

It would seem a Dual-Ratio rear would be needed for such an event. Too bad it's not a 32 as 31's did not have dual ratio. This will probably not be a high speed car with the current gearing.

Hi Mike,
Thanks for your reply.
The shorter shift lever allows a hi low range selection, correct? I assume this is a hi lo drive option within the design of the transmission. (The car does not appear to have a Columbia 2 speed differential)

The short lever is a freewheeling lever allowing you to shift 2nd and third without a clutch.The two speed lever was on the dash but not available until 1932 8-100a model. Randy

Thank you Randy.
Can a 2-speed differential be retrofitted to the '31 car or is this folly? Anybody done it?

It can be done. There are several different two speed ratio's, and you want a 8 cyl. two speed not a 6 cyl. one. If you are contemplating this change be sure and do your research on what ratio you want for your use. Also beware that the two speed is a weak point in the drivetrain. There is also a person who transforms a single speed dif. with a 9 inch. Ford and thus allows about any ratio you desire. To give you some idea I havr a 4X30 low range Dual-Ratio in my car and in high range I go 60 MPH at 2300RPM.
