[Vwdiesel] Alternator lower mount becoming oblong

[Val Christian]

Related, but not an altenator bracket...

Some of the old compressors had "oversize" holes.  I reality, they were
missing a bushing.  Without the bushing, they would elongate the hole in
the Al casting, and things would tend to fall apart readily.  The last
car I recall having this problem was a 80 Rabbit.  The newer cars seemed 
to not have that bushing.

I think Roger B or someone made a repair by drilling a bigger hole thru alternator case and support bracket then putting thru a larger bolt? This is engine with airconditioning using the big support bracket. Seems like it might be difficult to drill out a straight hole thru the support bracket while mounted in vehicle. Milton.
