Nope . (LS1 on top, stock on bottom) The 1LE is in between those two in size.

so then the LS1 can be used with an LT1, but not vice versa? Or are they swappable?

LS1, 1LE are both swappable. Same on 3rd and 4th gens.

87DJP2001: I was not absolutely sure on the actual diameter or I would have posted such, sorry. I didn't want to give out inaccurate info.

I think you did get the answer......the only Alum Ds that came with the LT1 stock, was the 1LE Ds. Yes?

Ok. [retreives vernier caliper*trudges out to shed* finds stock d/s*takes measurement*returns to internet*]

Stock is 2.5"

Where else are you going to get service like that?

I'm just really bored and feel like being a smart a$$ to my elders, so the correct spelling is furlough.
