My 72 charger 340 has the inscription 'use with 340 cast crank' on the front damper. Years ago I had Chrysler replace my transmission. Now I wish I had the original back, but now I would like to put the correct model with the closest date code I can find. Could I get some help on this. I think it would be either the 3515843 or the 3681952. My car was built at Flint on June 01, 1972. It has the rally package. From what I can find on-line it looks like the 3515843 was for early 72 8-340 w/o weight provision, and the 3681052 was 72 8-340 w/damper weight provisions. Does this matter and is the fact my 340 has the cast crank indicate I should go for the damper weight provision 3681052. Does this refer to the torque converter or the trans itself?
