I have a friend with a SBC in a 49 Olds that has had two alternators fail within 2 years. The alternators are part of a March Front Drive system and are mounted with the back of the alternator almost against the front of the cylinder head. There is no bearing housing sticking out the back. When the first one went out, the only one in the state of Ohio was at Jeg's in Columbus. We drove from Cincinnati to get the replacement for $350+ and now a little over a year later it has failed. Anyone else having issues?? Any solutions??
