I have a 1975 292 L6 in my 46' Chevy pickup. I purchased a A/C compressor bracket ($135.00) for a Sanden 508 from Davis Speed Equipment (608-469-4927). It is very heavy duty and is very adjustable for pulley ailgnment. After much research, he is the only one I could find that manufactures them 292 L6 specific. Note: I tried one for a 250 L6 and decided to replace it due to the look and fitment. I plan to have mine chromed because I think it will compliment the engine bay not detract from it.
