Jack shaft different lengths

[bigbarneycars]

When was the change made from the early(Shorter) to the later (Longer) Jack shaft. This is not a test, I'm just looking for some basic information. Thanks, Jer

Jer,

Are you referring to the intermediate axle shaft? I thought all were the same AA,E,G,HJ,K,P but L-body was different?

Of if you mean the long vs short pass side axle, those were different if it was a turbo/stick car it usually (not always) got equal length, and if it was a tbi/auto car is sometimes (not always) got unequal length
