Any other info can be had searching the forums. Try knuckle maching, titles only 

ORU(I think?) also makes a passenger knuckle with a cast-on steering arm that someone on here had a bunch of pictures of...I think it was MNSTRBURBAN or something like that, he's got a huge build thread here in the Garage somewhere.
Think he said the knuckle was like >$150, and sounded like a great setup for the price. Gets you a stronger than stock crossover knuckle for about the same price as doing a stock setup with a cheap steering arm, and there are no fasteners to loosen up and shear off.

Those are pretty trick knuckles and we've sold them when they're available, unless they've had them recently they've been on back order for well over a year. They will charge your card now though and seems like they say they'll have them every couple weeks![]()
