I am 99% sure these are Kenny-belle made. maybe 3,000 miles on them. Standard Bore. Some small normal scratches on skirts. They come assembled with stock rods machined for arp bolts. floating pins. I will look to see what numbers are on them to confirm kenne-belle. Never spun or reved over 6,000 - bought new by me back in the day. Pics on request. $275 plus shipping
