Can hacking be added to non-hacking Rolex 1520?

[cheld]

I'm collecting parts for a mid-70s gen/gen-spec 5513 build. To be period-correct it would have a hacking 1520. I've located an earlier, non-hacking version. Is it possible to make it hack? Can someone here tackle that job? Thanks.

Nope, look for the correct MVT mate.
I'm sure it could be done but the parts cost would be eye watering.
