ah, you mean the other number, ok, i´ll see in the garage and post here. Ok, here we go: PK 4058378 6552 2540.
Thanks for help

The link to MyMopar works for me but that number is skipped. Are you sure it's not a 4058376? If so it's a 1980 non lock up 727 used behind a 360. Thh next number is 4058383
