I think I could more easily make a Norton out of an Air Norton, if I needed to, than the other way round.

If it is an F-spaced model you need a spacer that is spaced for that. With a non-F-spaced, any spacer from another pickup that is regular spaced should work. Eventually you will have to file the holes to make it fit.

You can use a standard sized spacer in an f-sized pickup and vice-versa. However the keeper bar is a different story, unless this is the part where the file in the previous post comes into play(?).

That said, if the slugs are tapered then they will need to be replaced.

The 36ths replaced the vpaf/vhpaf set.

I'd go with the 36th neck.

Paf joe is lighter on bass, and slightly hotter.
