Below is a pic of my issue. I cannot confirm whether the AC aligned prior to my 2 year restoration but after putting the car all back together this fall, the AC pulley does not align with crank and power steering pump pulleys.

This is a '71 SS Chevelle 402 (LS-3).

Do I have the brackets and compressor mounted wrong? Do I have an incorrect compressor? The compressor model is 5910781.

Would someone be able to tell me what the measurement should be from the compressor bracket to the middle of the compressor pulley? This will help me determine whether the compressor is the wrong compressor.

The car is original numbers matching but it appears that the compressor may have been changed out in the last 30+ years.

Any assistance is greatly appreciated.
