Repco have them for 284 each, ebay brands are hit and miss, ADA are 1 year warranty then you have gallop with 5 years, then there is one in Sydney saying don't buy cheap poo, buy ours. Choice is yours.
I've had GSP driveshafts in my daily driver VY ute for over 6 years now without any issues
Part number is CVS-355 ……...Made by an Aussie company called AADI who specialise in CV joints & driveline products
You can buy them from Supercheap, Autobarn, or I've also seen them from online sellers for under $200 each
