RCCrawler Forums - Super Bully Axle Clock for Caster

Hi. I'm building a super around some nos super bully axles. I was told there was a thread addressing how to redrill the cases to clock the axles to get more case clearance and better caster settings, shooting for 20 degrees positive. It was supposed to include a link to the tool/gauge someone made to make it easier, and repeatable.

After a bunch of searching last night I found the thread, but there were not many details and the link to that tool didn't work. I gather the guy who had made that gauge/tool got kicked off for taking money and not providing the parts to the buyer.

Any old school guys who might have any info on this tool and/or the process? It doesn't sound too hard but why not things easier when possible?

Thanks
