Driveshaft specs needed

[Deleted member 214]

I have a 70 Road Runner with stock Dana 60. I swapped in the Keisler 5-speed nine years ago and when I move cross country I sold the stock driveshaft. STUPID :icon_hang: I am collecting parts in case I wanted to put it back stock someday and there is a driveshaft locally that may be correct, it may not. What is the correct length for a 70 Runner with 4-speed and Dana 60? Is the u-joint the same as on an 8 3/4? I think the Dana is longer and so would require a shorter shaft, and I also think the u-joints are larger, but don't know. Any advice would be appreciated!

the joints should be a 7290 and the drive shaft is generally 1" or so shorter. Sorry, don't know how long the shaft should be...

Thanks! You just saved me from buying the wrong driveshaft!
