Right now I have a guitar with a liscenced Floyd.
I'd like to replace it with the Floyd Rose Speedloader, or if that doesn't work at least the original Floyd.
Will I have any issues with them fitting?

Depends, I believe the FR Special is a direct swap, but most trems aren't just a take out/ drop in deal, even if they say so.

Easiest thing to do is just take measurements.
