BRAKE BOOSTER.
Wanting a late model 97 - 98 year model brake booster. It's the one that has a vacuum pipe coming out slightly toward it's passenger side and it does not have the check valve in the booster. Might have serial numbers like this on top of it.
834 - 02110
8205 And maybe a large number - 62 - stamped in paint.
This is from an SW20 Bathurst. 1997 - 1998.
Australian delivered GT would probably have the same booster too.
