Holden front end rebuild kits

I was looking at one of those ebay front end rebuild kits (http://www.ebay.com.au/itm/Holden-HQ-WB-Monaro-Statesman-Van-Front-End-Rebuild-Kit-/270829493059?pt=AU_Car_Parts_Accessories&hash=item3f0eb21b43 ) and wonder if anyone on here has tryed them out, Ie. what is the quality and fit & how do they compare with geniune for length of wear?

I think one of the guys in my club has had something to do with them, i will see him on Tuesday and try to remember to ask

Okay,Thanks for that James. I Look forward to his comments.
I know you get what you pay for, but I figure even geniune parts (if you can still get thm) are probably made in he same factory using the same steel anyway.
At least the ones on evilbay are greasable which might help them last a bit longer ...Perhaps..Lol
