7260 big enough???

Clay/Myron as well as others I respect and appreciate your opinions.
Myron would a solid U-joint be practical for street application with a 4spd? I will put less than 1k miles give or take on this car a year. But it will see some hard launches as we all know a 440/4spd Barracuda will be driven and not towed, LOL. And it will see some hard launches at a local dragway.

Clay you read my mind in telling me that not all are splined the same and that before any yoke is ordered I need to remove the current yoke and count/mic it so I am getting the correct replacement.

My heart is telling me to go with a 1350. Kind of one of those one and done situations. Being I am swapping from a SB to a BB in this car I figure the current drive shaft will need shortening. So why not upgrade. I may talk to someone at Randy's ring and see what they can do for me. Thank you all again:)
