This is a New Old Stock transmission case for T-90 transmissions. These cases are for the 4 cylinder engines used 1945-1965. Remember the cases are original from Willys so they do have some surface rust to them but can be cleaned up. On later transmission cases 1966-71 had a different adpater plate and the back hole on this transmission measures 4 3/8".
Note: These can be adapted for the L-226 6 cylinder engines by drilling and tapping the holes for the clutch linkage on the drivers side.
1 Required per Jeep.
