Lesson learned today, before purchasing new parts to modify an existing component, strip said component and check exactly how its made......... Dumb mistake and it was obvious as soon as I started to strip it....... 
 
 So back to the standard Thundercat bars. I still don't understand why they're so short. I thought it was because they'd been cut down for track use or something but it wouldn't be possible without to much work, and after stripping them I don't believe they've ever been apart, grrr.
Anyone have a set they can measure from clamp to end of bar?
