Longest sentence ever. The fix on a stock centerlink is to bore out the tierod studs on them and install a spherical bearing in their place, and use through bolts to attache it to the pitman/idler arms.
There's a banner ad running on my website (
www.nissan4wheelers.com) for Hoohaa centerlinks where with a core, he'll sell you one already machined for $225 - pretty cheap when you look at the price of other kits out there.
