What yoke and U-joint is needed to for the 4l80e swap on a 2wd rcsb without shortening the stock 4l60e driveshaft?
So far I have come with part numbers on yokes but not sure if they will be a direct fit on the 4l80e
TH400 slip yoke part # AAM 40032054
Neapco N3R-3-9161X yoke
Silverado:6.0 LQ4**4l80e T76 FM Turbo*** -efans EFIlive tuned-TrueTrac
Camaro: MTI x1 cam, MTI Lid, Free flowing exhaust
Never heard of being able to do it without shortening the shaft. Bump for somebody who has done it.
idk, had to shorten mine an inch.

The difference between winning and losing, is having a 2nd stage.
I used this one and did not have to cut the driveshaft.4L80E Performance Transmission from PATC ,4L80E Go to #72 on this page
depends on what driveshaft you have. If you have the aluminum shaft you probably have 1310 joints, 1.062" caps. There are two different size TH400 yokes, one has 1330 joints and the other has 1350 joint. There is a conversion ujoint from 1310 to 1330 and another one from 1330(1-1/8") to 1350(1-3/16"). I bought the longest one Spicer makes in 1350 size. It was about an inch too long so I cut 1" off the yoke.

Will this fit on my conversion to the 80e?
LS Series Flexplate 12621399 - Crate Engine Depot
Just found the hard way converter not bolt to LS flex plate, and stays way too far.
wow, that looks extremely weak. You need the flexplate, spacer and longer bolts. Since that all comes with it, that is one hell of a good price.

This is for the earlier model 80e transmissions with the non-LS1 flexplate
