So im having fitment issues with the torque converter. the blue torque converter is a new b&m 2400 stall converter and the older rusty one is the one that came in the car. i was told that the b&m stall converter fits 350 and 400 transmissions. the older torque converter goes on with not real issues but the newer one will not go on at all. i was thinking that when you look into the hole the larger spline set is farther back than the newer one i hopefully captured the difference in the photos attached to this. any help will be useful thank you.
