I was trying to save some time but a driveshaft is only a weeks time to get shipped , the Dana 60 has the 1350 yolk or U joint , the K member is factory Dodge and the transmission is a 727 so I guess they need the measurements from the end of the transmission tail shaft housing , if anybody has that measurement please post it , thanks.

You don't have a factory yolk on the D60 so using the factory measurement is not prudent unless you can confirm the specs of the 7290 yolk and a 1350 yolk are identical as installed? Also you don't measure from the end of the tailhousing , you measure from the center of the U joint slip yolk u joint hole to the center of the rear end yolk u joint hole.
Are you using a 1350 slip yolk too, you need it to make your measurement.
