How low before a 2 piece driveshaft is advised - The 1947 - Present Chevrolet & GMC Truck Message Board Network

So.... Looking at all the LOWWWW trucks Ive noticed the one thing most (not all) have in common is the use of a 2 piece driveshaft. Assuming this corrects alot of binding/pinion angle problems. So at how low is it recommended to change? Im currently at 5.5/7 but getting ready to go to 6.5/8. Ive noticed most of Delmos trucks have the 2 piece as well.
So hopefully you guys can shed a little light on this for us. Any things to take in to consideration when switching to one or things to look for or even the right way to measure for one etc. Your knowledge is much appreciated.

Good question, im also interested in finding out as I'm close to getting a driveshaft and I'd like to get the right one the first time around..

The reason is because eventually the driveshaft will hit the cab floor. So your options are to tunnel the cab floor or run a two piece.

My 66 lays frame with a one piece. Did'nt do anything to the cab. Wheel/tire combo is 30" tall.

Kasey, mine only has one pc. shaft. My floor hump was grafted in from a donor vehicle though. I have heard that high hump trucks can lay rockers without modification to the hump- but not seen one.

and mine is this low:
