For the time being I want to keep my halfshafts as you never know what comes next...
But:
You can replace it ALL with ordinary Series Three or Two HCPU parts.
No problem, I did just that.
Santana fits, too. My husband has tried that.
Forget the hom,okinetics, they just make life for expensive. A lathe and two seals will make a uni joint type halfshaft fit in a Stage One.
