Lens elements of that era's Nikkors are not drop in replacements for each other. So said a Nikon School "professor" many moons ago. I would imagine it would still be an improvement over what you have, going by the fact you want to try the swap at all.

These lenses are still not too expensive, but they seem to be going up at the various venues. Maybe consider just buying one. Good luck and let us know how it comes out.
