Ok, so I purchased a set of floorboard extenders from harleygoodies.com and they showed up just a few days later. Looked to be a really quick mod, just removing the two original bolts, adding spacers, and using the longer chrome bolts supplied with the kit.
Right side went on in under 10 minutes, the majority was working the odd angle to get the inside bolt. Left side was a dog to get off. Had to break out my 2' torque socket to get the leverage. Was in the process of installing the new kit and, with just a fraction of an inch to go, had to torque the new bolt and snapped it off.
So I spent the better part of two hours drilling with a carbide bit and a touch of motor oil to keep it cool. Finally made it through the bolt, widened the hoe with another bit, and started using a reverse threaded bolt extractor. A couple of turns with that and SNAP, broke that bit off in the hole of the original bolt. WTF??? So another hour of the carbide bit and made NO progress through the new piece. Just gave up for now.
Any ideas as to how to get that out? The original bolt is really cranked in there and now I need to deal with an even stronger broken removal bit in the hole. Im also worried about breaking a new boot next attempt.
Simple bolt-on upgrade my ass.
