Hi, John,

The 3.54 gears were originally supplied by Phil Hill. I don’t believe that he has any left.

The current supplier is Phil Bray and the ratio is 3.85 I believe. This is a little better compromise if you live in mountainous areas.

I have a 3.54 set installed on my ’29 133 Club Sedan and we can cruise comfortably at 60 mph (in the flat midwest). Our original gear was a 4.58 so this is like another gear in the transmission. The coolant temperature is significantly lower and of course the mileage is better.

The Phil Bray gears will fit your ’31 without any modifications. Phil is a member and is in the directory.
