This seems like a perfect thread to hijack, since I've just gone cross-eyed reading dozens of posts while trying to find the right search keywords for this. Thanks, @pdXammo ;-)
Anyone know what the difference is between the *rest* of the spec-B rear arms, besides the aluminum rear trailing arms (RTAs)? (well, I know the uppers are also aluminum).
AFAIK, some of the arms and bushings are interchangeable, while others call out as specific spec.B parts. If I change the RTA, can I keep all the others stock, or will it eff up the geometry?
Are they different length? Hollow? Secretly blessed by the Illuminati?
They're nice and cheap on eBay these days, and I'm planning to get either (1) just the trailing arms or, (2) get a "whole set" like below.
Pictured and applications, best as I can tell:
"Support brace" (bent-elbow, top-left, looks like hollow steel, alternate P/N for spec.B )
Lower-front lateral link (left, hollow steel, spec.B alt P/N )
LFLL bushings (inboard is same for all models; outboard at RTA, spec.B alt P/N )
Lower-rear lateral link aka "toe link" (steel, same for all)
LRLL bushing (inboard only, same for all)
Rear trailing arm proper, with RTA forward bracket and bushing (bracket and bushing alt spec.B P/N, of course)
Upper lateral link (right, aluminum. spec.B alt P/N)
ULL bushings (inboard same-for-all, outboard spec.B alt P/N)
