Question, why don't you guys use the TDMImports, or 2J Racing Bump Steer Kit, it's pretty much the same thing, and the 2J Racing one fits all B chassis to my knowledge, as well as the P10, because I specifically asked them about it for my build... Below are the links

2J Racing:
2JR Bump Steer Kit V2 (b13-b15) - Suspension & Chassis
I hope this sheds some light as it seems you guys are looking for competition quality outer tie rod ends, and the ones I posted even help adjust the angle at which the tie rods are on a lowered car so you don't have as much bump steer on different types of track conditions.
Good luck :-)
