They don't appear to be bushed, but you are asking a reasonable enough price for them, someone could have them bushed and have a really very nice set. Not that they are not already nice. Bushing them is really not necessary, but would really ad to the durability. They would last a very long time. I believe Tim is correct also in that they are Crane Gold rockers. Perhaps some older units from Mopar Performance. They for Crane to anodize them blue since that was "their" color. Sorry for the extra comments on your for sale thread, but I thought it relevant to mention all this. You have some pretty nice stuff at a pretty good price. Good luck!
