Which alternator do I have?

[Erik R Addy <erik@aero.und.edu>]

My "new" 200tq has a bad alternator and I need to find out if it is the
old 90 Amp (?) unit or the newer 100 (or is it 110A?) unit.  Is there a
certain VIN number where this changed?  Hopefully it is the same as my
"old" 200tq, because I still have the alternator off that.
Oh, and has anyone else noticed corosion on the altenator ajusting
bracket so that the teath on the ajusting nut don't work to well?  Is
this big $ to replace?

TIA
