Many of the 360's had a spacer from the factory that was a source of vacuum for the PCV. The spacers would corrode, causing an idle problem. Since you didn't mention that, you may have the only one that hasn't corroded yet. There were some phenolic spacers available that had the vacuum hose barb on the back. Look for one of those. I don't know if they were aftermarket or factory for one year. If you have a vacuum source on the carb, you can make a spacer out of hard wood.
