I was told I had a 4.11 posi in a 61 driver I recently purchased, but would like to confirm. Cant make out the stamp on passenger side of axle but have this on the drivers side
K663
B789312
GM 1/2 P
Anybody got any clues?
Also can't get to the engine codes on front of block but have 3970010 6 GM on drivers rear and f220 on other side. Supposed to be 1970 LT1 any other way to confirm?
