Oh dear.  Memory, they say, is the second thing to go.  I forget what the first 
was....

As I seem to recall, I took the pully off the generator and it installed on the 
GM alternator, which is the unit that Dan Masters recommended and is the common 
one for the conversion (Don't ask, I forgot the number!).

I just checked my receipt box, and it was the stock pulley.

What did you do to still use the thick belt?  Also, more for the other 
listeners on this call :-)  Has anyone tried the denso alternators, they are a 
much smaller package.  My '95 K2500 had one but it had the serpentine belt 
pulley on it so I wonder about the conversion.

I'm coming in on this late, but what the hay, why change the life cycle now, eh?

I stayed stock with a rebuilt generator...for a time.  ..Until I ran the car in 
the fall, driving to work in the morning in the dark, driving home at night in 
the dark, and finding that using the lights and running the motor left me with 
a dead battery after, I forget, two weeks?

Did the GM alternator conversion and never regretted it.  Well, except when I 
discovered one of the wires I'd used didn't stand up to vibration because the 
strands were too big, leaving me beside the road fabricating a new connector.  
Now cured and forgotten.

I didn't bother with the thin belt conversion, but don't see why not.
