RE: trex 450, hbk2 interchangeability ?
Man, wish I'd known earlier that you could use the trex spindles like that. I've been waiting for weeks for someone to get the HBK2 spindle in stock and just ordered it yesterday.
Think you could use that spacer ring that comes with the trex spindles (forget exactly what it's called) instead of the extra o-rings?
Anyway, thanks for the info, I'll give it a try next time.
