Hey Darrin, I bought a brand new S2 Stagea handbrake lever, through japanparts.com. Was around $140, and another thing, I've enquired about stagea parts through Nissan Aus, and they've told me they're not available, then I've enquired with japanparts.com, and they've been able to supply them.
I'd give them a try, takes no longer than through nissan aswell, bout 2 weeks.
