Default U-joint help

Removed th350 and installed th400 in our 74 formula . Does anyone know of a u-joint to make a 400 tail shaft work on the 350 driveshaft.

1. I'm surprised the driveshaft would be the right length.

2. There's a hundred U-joint part numbers. What you need depends on what you have. Any parts store can fix you up if you bring in the parts so they can measure and compare. A local driveshaft specialty shop could do the job faster than the parts store in most cases.

427 BBC 350 trans came out. That set up must be a little longer? not sure why they are same lenght. 48.5 in center cup to cup. Think I need Moog #HMG372? Find out in the morning when I pick up at Napa. Jim

I think one of these will work:

Napa PN 372
Precision 372
Neapco 3-3130
Spicer/Dana 5-3022X
