I bought my 05 UC used and the prior owner sold the lowers and engine guard (replace w/Mustache Guard); I posted that I needed color matched lowers (Black Cherry) in the WTB section and within a week I got a PM. I bought the color matched lowers, glove boxes, caps, etc. with the stock engine guard for $400.
I dont expect to find a color matched set as my Street Glide is Dark Blue Pearl. The set I found are not the right color, dont have caps or glove boxes but they guy wants $125 for the set.
