1973 Scamp Rearend question

Not to hijack the thread, but will going from a 7.25 to 8.25 require a driveshaft modification?
I'm in a similar situation with my 74 Scamp.
I actually have an 8.25 lined up with the ubolts, perches, and whatever else...just not sure about the drive shaft.

Nice looking car, btw. :)
