BTW its 50" from backing plate to backing plate, perfect replacement fit on the 49 plymouth
If it's a GM, get out your wire brush and clean off the area on the bottom of the housing right below the cover. If you find some numbers they can be translated to tell you which rear end it is, ratio etc. I don't have the data at my finger tips but can find it for you. Post the number and I'll look it up.
