Nope. All common parts usually.
And yes, to my knowledge anyway, to use the larger joints in the front axles you have to get the larger axles.
Spicer numbers for all the stock Dana 44 joints are:
Front axles (all 66 to 77 axles) : 5-260x as SpareParts said. 5-260-1x with the lube fitting.
Front and Rear driveshafts at the diff yokes: 5-1200x
Front and Rear driveshafts at the double-cardan (t-case) end: 5-433-1x
U-bolt straps, in case you need them, are 2-94-28x (pair) at both ends.
Hope that helps.
