reference the letter and you have your original ratio.
Need to check stamp on axle housing and possably remove diff cover and check the stamping on the ring gear to fully document.

Quick reference from an earlier post. 1st letter is type; U= open V= posi.
2nd letter is ratio A=2.41, B=2.56 ......G=3.42, H=3.55, J=3.73, L=4.11 There is an off chance is it's marked 4.11 it could be a 3.90 or a 4.33 (dealer installed) If it's a 4.11 you may well have a M21 (close ratio Muncie)
