Had a hellish time getting the wishbone back in with the new bush's on.
The smaller front wishbone bush is a tight fit but the big rear one is a loose fit. I think i was premature with my ranting about the rear bush having some play in it , when you try one in itself there is a loose fit but with the tube and the other half all together it is not there anymore . The problem i had with the front bush was the bush would pop out slightly cause it was such a tight fit don't know if its cause i used too much grease . when you overcome that and get it into place it's fine .
A bit of wrestling involved but it does fit . don't know if genuine vauxhall are the same hassle fitting .
I can say for sure FAI wishbone are solid with or without powerflex bush's . The original bearings are solid the wishbones took a good battering to get into position. Would obviously be easier without the powerflex bush ,
So i would not hesitate to recommend them to anyone thinking about using them. can get them in the shop
