Talked to A and A

I've learned to never say never concerning overlap but the 2-3 shift overlap that is a problem with 727's isn't nearly as much of a problem with 904's so you probably won't have an issue using a 5.0 lever. Do you have any idea what lever is in it now? If it's a 3.8 or 4.2 lever you won't see all that much of a change. If it's a 2.9 (very common factory lever) you'll see a nice change. Will it be enough to make it chirp 2nd gear? No idea, but it should firm up the 1-2 shift a decent amount.
