Madcatz SF4 Sanwa JLF question

I could not seem to find this answer after searching. But I am curious, I notice that reading on some of the other websites on just ordering the sanwa parts themselves, that they were 4 way and 8 way interchangeable.

Is the sanwa balltop in the madcatz SF4 the same way to? Can it be changed to 4 or 8 way and vice versa?

Thanks.

Haha thanks.

Should have search with four-way not number and stuff.
