A/C pulley replacement swap

Unfortunately you cannot. Two reasons. First the pulley style is different. The 2000 uses a V style belt. The 2003 uses a ribbed belt.

Next the pulley offset is different so even if you switched the pulley, it will be out of line and the belt will keep jumping off or shredding.

Lastly the compressor itself may not actually bolt up. I am not sure about this but it looks like they are physically different.

Please see the info below for more detail.

Thanks
