Driveshaft length? 4l80e & 8.5"

[Schamsy33]

I am hoping someone can help me figure out what length driveshaft i need.
4l80e swap with 8.5" rear end. I know the 4l80e with factory rear end requires a 3.25" shorter drive shaft. What does the 8.5" do, if anything, to the length of the driveshaft?

I do not have all components on hand yet or I would simply measure. Hoping to get driveshaft ordered ASAP.

Thanks

Go to this site. It shows you how to measure. But you would need the rear end and trans. installed. They have made SyTy driveshafts before. They may know if you call them. They have good prices. Driveshaft & Component Measurements | D&R Driveline Inc

You should verify but I'm 99% sure that 8.5 requires a 1" shorter driveshaft.
