So after deciding I need to replace the ball joints on my 85 745t I decided to give all the bushings a quick inspection. All seem in good shape with the exception of the upper sway bar link bushings (name?), which are cracking and seem extremely worn (although they aren't in danger of falling off in the immediate future).

My question is which bushings do I buy? I've found that most BB posts favor using PU bushings for a longer lifecycle, but are there specific bushings to stick with?

The picture at the bottom of this post are a pair of bushings made by APA according to the parts catalog I order from... is that supposed to be GAPA? Or is APA another company? Are the yellow ones PU or normal? Anyone ever use them? I noticed FCP sells the normal black ones (Scan Tech) and a pair of red ones with no manufacturer listed... are the red ones GAPA?

All these parts sources seem pretty reputable and the bushings are cheap, so I figure I'll be good either way. However, I'd obviously like to avoid changing these again in the near future, so if someone could point me in the right direction I'd appreciate it.

Thanks,
