8L90 Slip Yoke Question

[84evelynrose]

Really hoping somebody can point me in the right direction. Swapped an L87 6.2 with 8L90e 2WD into my 84 square. Trans is from a 2018 Escalade. Having trouble finding the correct slip yoke. Slip yoke I have is 32 spline and measures diameter 35.93mm. GM Part number is 12471638. I measured the inside diameter of the output shaft and it's 35.84mm. Even local Chevy dealer can't tell me if I have the right yoke. Maybe I just don't know how to install it. Not a trans expert by no means. I'm ready to order that drive shaft!

Not so much a question I guess. I'm hoping someone knowledgeable could help me with identifying the correct slip yoke that'll fit a converted 8L90 from 4WD to 2WD. The yoke I got (#12471638) is close but a hair too big. Part number stamped on the output shaft/tail is 24272517 if that helps. I've called around a lot and even if you could point to another source for information that would be helpful. Mike, I really appreciate you replying man. Thanks.
