Are there any good sources for these? Retail chains and LMC don't have them. thanks | | | | | Joined: Sep 2006 Posts: 2,393 Shop Shark | | Shop Shark Joined: Sep 2006 Posts: 2,393 | Jim Carter and a few others sell them. New,, about $40
Used, about $15. They are on EBay alot too. I don't think it's a must to be year specific, but I don't know what year span to tell you. Others here probably can.

My 62 has the advance low on the dist. shaft and are not a very popular item to reproduce. I'll know more about what's wrong with it when I break everything down and clean it up. I know I'll dwell on it while I'm doing the body if I don't fix it now......yep, I'm nuts. | | | | | Joined: Sep 2001 Posts: 29,269 Bubba - Curmudgeon | | Bubba - Curmudgeon Joined: Sep 2001 Posts: 29,269 | | | | | | Joined: May 2010 Posts: 47 Wrench Fetcher | | Wrench Fetcher Joined: May 2010 Posts: 47 | | | | | | Joined: Nov 2004 Posts: 1,552 Shop Shark | | Shop Shark Joined: Nov 2004 Posts: 1,552 | I just purchased two from my local parts supplier...East Side Auto Parts (Advance Auto Parts) for $16.95 + tax. I bought one to install and the other as a spare. Most auto supply stores have them. | | | | | Joined: Aug 2008 Posts: 116 Shop Shark | | Shop Shark Joined: Aug 2008 Posts: 116 | Every vacuum advance unit that I have ever seen on a 235 kinda' wiggles back and forth when you rev the engine. I would think a nice, smooth, fluid motion would be ideal, but maybe not on these old engines...Is it supposed to be this way, or has every 235 I've ever seen had a vacuum leak? Opinions welcome.
