Why this exists
The answer you need is in page 7 of a 2011 thread, behind three wrong answers and a follow-up asking if anyone ever figured it out. Trail Manual entries are structured around the question, not the conversation that happened around it.
Most automotive content gets paid to recommend parts. Trail Manual has no sponsored content and no paid placements. When something is overpriced or not worth it for most builds, that's in the entry. The goal is your best decision.
Factory manuals tell you the torque spec. They don't tell you the OEM bracket costs $280, the quality aftermarket option costs $65, and the cheap one fails in two seasons. Every entry includes real current pricing and what you actually get for the difference.
