Default What driveshaft??/

Changing from a 4l60e to a 4l80e.

Is there a driveshaft that will work ... or will I have to have mine shortened?

I have that writup and was counting on it but didn't notice they were working on an Avalance and the driveshaft is a 1 piece. Thanks for trying.

When I did the 60 to 80 conversion the drive shaft shop wouldnt shorten my factory shaft they built me a steel one instead I forget the part # for the yoke I used though.

Would a driveshaft from a heavy duty truck fit? The wheelbase appears to be the same.

Still need to make a decision on a driveshaft. Any input? Would a driveshaft from an extended cab hd truck work?
