+1 on the old seals. They are not the best.
Just a tip - when fitting the new nitrile seals (particularly to the HSN) make sure you put a dab of lube or O Ring grease on them before installation.
With the newer GX double O Ring HSN's the upper (last O Ring to go in) can be very tight, and it is easy to damage or shred this O Ring trying to put it in dry.
