If your spring perches are the same distance apart you might be good to go. If not, what I would do is measure the inside of the tires to make sure they will clear the springs first, and if so reposition the spring perches on the axle. Will probably need to get your drive shaft modified to fit the new dimensions, and I'd think your brake system may need a boost to push larger brakes on a later rear end.
Just me thinkin out loud tho. grin

I dig all cars, old and new, whether they were hammered out of American iron, German steel, or Japanese tin cans. Being unable to appreciate them all is missing out on a world of great things.
But thats just MY opinion!
