Alternator help
I need some help with which alternator will fit my vehicle. I'm looking for a chome alternator to replace the one i have and there are a couple of people selling them used. The problem I'm not sure what will work. I have a 2000 and i don't think i have a clutch type but i'm not sure. The alternators i'm looking at are for years 2001 and up and i know one of them does have a clutch. Could someone explain the differences to me and hep me understand the difference and also what will work on my car? I tried to do a search but the search function has been acting weird lately and when i type in "alternator" the threads that come up have nothing to do with alternators.Thanks for any help or replies

Intermittent Accessory Drive Rumble During Garage Shift (Install New Generator) #99-06-04-029A - (11/29/2000)
Models: 1997-2000 Chevrolet Corvette
with 5.7 L Engine (VIN G -- RPO LS1)
and 4L60-E Automatic Transmission (RPO M30)
--------------------------------------------------------------------------------
This bulletin is being revised to update the correction procedure. Please discard Corporate Bulletin Number 99-06-04-029 (Section 06 -- Engine).
--------------------------------------------------------------------------------
Condition
Some customers may comment on an intermittent accessory drive rumble noise when performing a garage shift and/or during parking lot maneuvers, such as turning the steering wheel to the lock position. This noise may also occur when turning on the air conditioning at idle conditions.
Cause
Engine idle speed may drop below 600 RPM while performing a garage shift, turning the steering wheel to the lock position, or turning on the air conditioning. This noise may be amplified by a large rate of change in engine RPM. This condition can also be aggravated by different low engine RPM driving conditions.
Correction
A new Generator with Decoupler Pulley and reduced damping Accessory Drive Tensioner was implemented for all Corvettes with automatic transmissions at 2001 SOP (Start Of Production). The generator with decoupler pulley is used only on Corvettes equipped with an automatic transmission. The reduced damping accessory drive tensioner is used on all 2001 Corvettes.
The new decoupler pulley generator and tensioner assembly should be used to service 1997-2000 Corvettes with automatic transmissions that exhibit the idle rumble noise. Refer to the Engine Electrical and Mechanical sub-sections of Engine in the Service Manual for generator and tensioner replacement
