1916 U-joint Interchangeability

[26Willys]

I have a '16 roadster with a worn out u-joint and a spare u-joint from the early to mid 20's.  The newer u-joint will fit the transmission and driveshaft just fine, but is slightly bigger in diameter. Has anyone used a newer joint in an early car? It seems like it would work, but I'd hate to get it all together and find out its hitting something inside, and then have to tear it back apart again.

 

Thanks

It turns out a 20's u-joint will not work on a '16. The newer u-joint is slightly bigger and longer. The housing hits the back of the u-joint before it can be bolted all of the way down.
