Question 49/56 Ford rear gear pass car

I have a friend who purchased a 55 ford.This is a nice survivor car and would like some time in the left lane The question is are their any ratios other than 3.9 or 4.1 This is for pass car not station wagon.I have checked every one I can find and all have those 2 ratios. The owner 74 yrs old does not want to change to 9 inch or other 3rd member assy.Any help would be appericated. Thank You.

 

k9racer, the Hollander lists these other ratios for 55. Cars with auto trans had 3.22, 3.30 and 3.55. Hope this helps.
