one piece driveshaft

[TylerZ281500]

if knowledge serves correct, your 2wd extended cab shaft is at the verge of being too long for a single piece. the only way you might be able to swap to a single is if you run a 5-6" aluminum shaft. i dont recall as that wasnt my expertise, i stocked all the parts, physically built the shafts and balanced them but just started getting into the physics of building them.

so best bet call your up a trusted driveshaft shop and ask them, youll need a measurement from face of your pinion to the back of your trans to have one properly built.

The newer trucks run a 1 piece driveshaft but like you said they are 5" or 6"

A friend has a 99 OBS suburban that we measured the on and it is shorter.

Here is something to think about. The Suburban has the same wheel base as the ECSB.

Negatory. Suburban is 131.5" wheelbase, ECSB is 141.5"

yeah ididn't really think about mentioning drivetrains. i've never been under a gmt400 until i got mine and been doing the work to it, so i didn't know any different. we was just thinking but are on budgets so not a lot of play for parts. thanks for all the info guys.
