I have a turbo 400 Chevy ****** and need a slip yoke for a 1929 Chevy coupe im building. I have a yoke that fits the shaft but is too small for the seal so I made a trip to the junk yard and only found pickup yokes that bolt to the tail shaft so i looked my ****** over and see that the shaft is drilled and threaded. So my question is do they make a slip yoke that is big that doesn't bolt on or do I need to change out the tail housing. Its a th 400 short shaft. Or do they make a different size seal and bushing.
I ran into the same problem with an off topic vehicle. The guy who builds our driveshaft's locally built me one with a slip yoke, it was a short shaft and didn't need a carrier bearing. he did suggested that the bolt on type yoke would work with a freeze plug installed in center of the yoke and or welded. I voted against this for other reasons but If this approach was done I don't see why it wouldn't work. The bolt on yoke does seem to have a shorter collar though. good luck.
thanks didn't think of that. I don't see why that wouldn't work to weld up the hole just have to watch the drive line lenghth shouldn't be a problem thank you.
Early nailheads 400's had a yoke with a smaller outer diameter then the chevy's. I should have a chevy yoke lying around here that I will trade with you. Or if you find one locally I would like to buy the yoke you have. I have a couple of nailhead 400's without yokes.
If you are having a problem finding a proper slip yolk you may have a turbo 375. They came in He****s and ambulances. I don't know the real difference between a 375 and a 400 maybe a ****** guy does, but I do know that you can change the tail shaft housing and use a 400 slip yolk.
