drive shaft LWB 1 PIECE OR 2??

[78-5.3]

ok so im trying to organize my drive shaft before i lower my truck im waiting on the flip kit and spindles!! my question is my truck has the gen 3 5.3-4l60e and sits back a couple of inches from standard, now my factory 2 piece driveshaft is too long if i get it cut down the 2" its $140 bucks ,then i need a new center bearing thats 35-75 bucks and i need a yolk mine is missing so what ever that cost !
now there is a driveshaft at a local junk yard that will fit but it needs the rear universal joint replaced no big deal for $75 BUT ITS 1 piece , so i need to remove the center bearing suport under the truck (rivets sux) now if i lower the truck with the center bearing suport removed how far can i lower it before it will foul anything ? has anyone got a LWB thats lowered with a 1 piece im going like 7 in the back !!!should i just leave it 2 piece or change it with a 1 piece ???????

I used a 90 1/2 ton suburban drive shaft and yoke (700R4 & 4L60E yokes are interchangable) on my 85 and didnt do a thing to the drive shaft. So i whould think you chould do the same with any drive shaft from a 82-up 700R4 equipped LWB truck. I whould shy away from building a one piece driveshaft that long

Did you convert your burb to the 5.3 and if so did your drive train come back like mine ?

Yes i have a 5.3/4L60E in my suburban. I lined the shifter linkage to the trans strait and thats were the engine was placed

Maybe you could run a Suburban drive shaft. The wheelbase is 2" shorter than a longbed truck, which is what you were saying needed to be removed.

i could but which shaft is shorter the front or back

[Pyrotechnic]

Yeah, you're right. Probably the back one. Unless Suburbans came with 1 piece shafts.

The best thing to do is probably to take your shaft and have it shortened. get new carrier and u joints installed at the same time. they will balance it as well. its worth the money then u wont have to worry about that d shaft for a very long. th350 and 700r4/4l60e yokes are interchangeable. the 700r4/4l60e is about 3 inches longer than a short tail th350 but within an 1/8 inch on the 9 inch tail shaft th350
