Re: 1967 327 Starter sources
Unfortunately, it's true. the 327 starter is tough to find. you might want to try some sources or clubs that deal with early AMC cars, such as Nash/Rambler. I think they had the same engine. Hemmings may have some sources or advertisements of shops that specialize in vintage starters, generators, etc. Specialty Parts in SAn Carlos, CA may be a source. I'm gussing this is not going to be a cheap venture. Swap a chevy 350 or AMC 360 and never worry about parts again. good luck
