I have a 1955 Ford wagon, but I'm not sure what size rear end it has under it ?!?! I'm pretty sure it's the original housing, but supposedly the gear has been changed out. It does have an inspection cover on the back, and I know the 9.0 and 8.0 don't have covers (i.e. early mustangs) What is the best way to tell one rear end from another, measure, number of bolts, any ID tags ?!?!

I need to change out the gear. It's a 4:11 !!!


Thanks for the help in advance,

- Mr. B
