If you can install the original rigid fork on it, I'd do that for sure.
There are a few shops out there that still have the tools to do it but you have to know where to look and would probably have to ship the bike there, which isn't cheap. Where are you located? Maybe someone here knows a place to do it.
Alternatively, some people use improvised tools to replace them. I'd prefer that those people who have done that instruct you in that.
One thing to be aware of is that you'll have to buy new bearings for them. They're basically toast after removing them. That said, if they're installed correctly, they'll never wear out or need to be replaced.
This website sells the MC1 bearings that you'll need:
