barrel

I have a DB30s (Metal fenders) that I just picked up and the brake caliper and brake cable were messed up. I got a cable and caliper off a person on here and the barrel end that goes in the brake lever is smaller then the original barrel. He said he took it off of a DB30s just like the one I...

I've tried tapered head sex bolt, barrel bolt, binding post, etc., but nothing is coming up. The barrel is 8mm wide and just shy of 1-7/8" (47mm) long.

I'm not sure what the correct nomenclature is, but i'm looking for a small tank like the one on Ron's Orange Mini. Someone know a place?? or if you don't know ron's mini, like this one... http://www.vintageprojects.com/mini-bike/pocket-bike0002.jpg
