I have a 82 PA P30 454 with the L O N G dip stick, if you want I can measure it if need be, shes sitting in the driveway waiting to go somewhere
Does yours or "did yours" go back in hard about 1/2 way? I have to use both hands to get it back in or it will kink.
Let me know if you still need the measurement.
(not sure if they will be close though)
