Dana Spicer 3-3-5571X transmission slip yoke 1350 series fits long tailshaft GM T-400, 4L80, 4L85 and others with 32 spline output
I used this one. I also have 1350 series u joints tho. Not sure what you have. This was the only yoke i found that was full splined and long enough to fit the whole output shaft rather than 2 3/4" of it.

I just run a used 80e yoke from junk yard or order one off ebay. Get the longest yoke they sell. If its to long just cut 1" off it to shorten it up some. ive done a lot of swaps like this without issues. u can get a napa 447 u-joint to convert to your stock shaft.

I got this one from a 4l80e truck but the moog 447 u joint won't seem like it will fit on the yoke anyone every had that problem

it should fit as long as u have the correct yoke from a th400/80e.

Yeah the yoke fits in the tail shaft perfect it's just the u joint is to short to fit the yoke good . Would it matter if the 4l80e yoke came from a one piece or two piece driveshaft

no it doesn't matter what shaft. The yoke takes the bigger caps with outside locks that lock into the yoke. The other caps if I'm not mistaken lock on the inside with a c clip. Are u sure u got a 447 u joint??

Luis3701

yeah I ordered it from autozone , Imma try the precision from oreileys and see if theirs a difference between them , it seems like the u joint series for the slip yoke i got it is a 1410 .

What ujoint did you end using? I'm having this issue the 447 won't work for me.
