Alex, look at the link below.
Toyo and Isuzu owner's have been using these since the 80's.
There are 5 companies selling these spacers for Pajero's (Montero JDM spec) in the UK/Australia for the past decade.
If balljoint spacers are as bad as you claim, then there wouldn't be 4x4 companies selling them as a genuine product.
You seem adamant about really bashing this thread, so as a gesture of good faith, I'll send you a set for free and you can see for yourself.
Toasty will get a set as well since he's been modding like crazy since the begging of time.
Both you guys shoot me a PM with your mailing address and I'll ship them out tuesday when I'm down in Seattle.
If you don't like them, ship them back. If you like them, then you can decide whether to pay for them like everyone else or keep them.
The slight taper is there to provide a flush mating surface with between the now raised a-arm and the balljoint. If the taper was not there, then the flat surface would push the balljoint outwards.
I would ship them with a disclaimer that is standard for suspension aftermarket components sold around the world.
