I bought a USA Curlee earlier this year which I still haven't quite decided what to do with.
Below are some pictures of the pickups and pots. I'd guess, and it's only a guess, that if your pickups were DiMarzio then the pots would be too, as they are in the USA ones.
This is the only pic of the rear of the PUs I've got but you can see they're different.
And of course we need the whole bass in it's slightly battered state.
As @Bassassinsays, if your PU work give them a go and see what they sound like. I think both pots should be 500k, coupled with the PU being so far back gives them a real aggressive, clanky tone. A bit of distortion and I think they sound fantastic.
