Got a question, purchased through a mail order site of a Subaru Parts Dealer. One of the parts I ordered was a 20 mm rear stabilizer bar for my Crosstrek. It didn't come with two new 20mm black rubber bushings. I'm pretty sure I order it as a kit, bar w/bushings. Am i'm to reuse the old OEM ones, which the bar is only 16 mm thick. Does it really matter?
