This was the part I needed for my '89 Civic DX with d15b2. The kit also came with 2 packs of lube although I hardly ever used 1! Installing was a lot easier than removing the original. especially in transmission. TIP: Lubricate the center hole of the new long sleeve to make it easier to slide over the flared end of the derailleur stem. Glue one side to the glue, then work the rest over it. Lubrication makes this task easier. Be sure to lubricate the bushings well at all contact points to prolong life and reduce noise. This is not mentioned anywhere in the instructions. I have friends who say their ES derailleur bushings fell apart after a year. I have a set for another EF and they have been working great for 8 years now. Probably because I greased them.
