OK i found a drive line, i think it came out of a 904, the tranny looks like a 904 as it has the hump on the left side, but any way's is it true that a 904 slip yoke wont fit in a 833 OD?? i am asking because i finally found 1 after looking for a few weeks for the 2wd project, they guy has no info on the parts ect ect an he lives 2 hours away, would really hate to jump in the ol gas hog lol an drive over for nothing ya know...

RR is right---wont fit....bob

correct,904 is small yoke

833/727 is the large yoke

they do not mix.

OK, can i get away with, taking a 727 slip yoke an putting it on the np435 drive shaft that is already under my 2wd??? or will the drive shaft to to short or to long?? if its to long i can always have it cut no biggie... i was told i should be able to just find a 727/a833 slip yoke an do it that way but just want to make sure before i go all hands in lol ... got like 9 days to build the truck hahaha so just trying to get every thing lined up...

if it has a bolt on yoke on the trans or xfer... no

if it has a slip yoke like a regular 727 long tail shaft... maybe

best ting is to put the trans in,slide the yoke in till it bottoms out,measure from center of cups to center of cups on axle yoke,then subtract 1"

I just went thru this with my 727 swap,my stock shaft would have fit but i have a flip flop on the rear with mono leafs and lift bars.

my shaft came up 2" to long so I am waiting for it to get cut down some. if it was a stock specs it would have fit just right.

IMHO,it is best to measure it to be sure. little long can break stuff and a little short can cause vibs and stuff.

see on my last thread a guy said i should beable to use the drive line that was already in my 2wd, i would just need a conversion u joint?? i am loading the tranny up to day an taking it with me to the J/y to see if i can find the right slip yoke that fits it, the owner said he might have one off some old 727's.. i never really looked at the drive line that was under the 2wd lol, the truck is out at a budy's, like i said if the drive line is to long i can always get it cut no biggie, the problem is if its to short lol...
