SOLD I have a set of 10 black extended bolts, shipped to me with some spacers this week. Size was in error, so vendor shipped the correct ones and said go ahead and keep these. I have no use so I'm selling here.
From the pic, the bolts (top bolt) appear to be roughly 3/4" longer than standard oem (bottom bolt), so I'm thinking they're for 18mm to 20mm spacers.
Will sell for $17, shipped to CONUS only. Bolts typically run $25-30 from vendors.
