Lynn,
What do the mounting ears look like on your Geo alternator? Basically, there's one
really big, heavy ear on the front case, and alternatively there's small ears on the
front and rear case. I don't like the "big" mounting ears for what I fancy to be
structural issues. I think they can "wobble" more easily than the ones with two ears
wider apart.
And my mount bracket lends itself to 2-ear alternators ... Jim S.
