I went out today and purchased some new strut rod bushings. I bought a set of TRW bushings. The sleeve sizes are 2-1/4 and 3 inch. From what I was reading with the Moog bushings you have to trim the 3 inch one to 2-3/4. Is this true with just the Moog bushings or all of them. On the kit to the frame it has 2 washers, 2 bushings, and 1 sleeve. The picture of the Moog setup there is 4 other pieces. 2 of them are nuts, but what are the other 2 pieces?? So would I need to replace the nuts?? If so is the kit that I have missing those 2 other pieces minus the nuts?
