I did a quick search, but did not find a definite answer. I have acquired a set of used lift springs for my recently acquired blazer. However they are in need of new bushings, but I do not know who the manufacture is. The bushings are yellow, so I supect they may be from Superlift. However I believe Tough Country used yellow as well. Can anyone tell me for certain who used yellow bushings? Thanks in advance for any help.
