Your options are:
* Fabricate a bracket: This is the most common solution. You'll need to find a suitable piece of metal (aluminum or steel), design a bracket that securely mounts the alternator in the space previously occupied by the A/C compressor, and have it welded or bolted together. This requires some fabrication skills and tools.
* Modify the existing bracket: You might be able to modify the existing A/C compressor bracket to accommodate the alternator alone. This requires careful cutting, welding, or drilling and may not be as structurally sound as a custom bracket.
* Source a used bracket from a non-A/C equipped Comanche: This is a long shot, as finding a used bracket from a similar-year Comanche that didn't come with A/C might be difficult. Even if found, it may require modification to fit perfectly.
Before attempting any of these, carefully examine the area where the A/C compressor was mounted. You need to identify existing mounting holes and assess if any are suitable for adapting to the alternator. Consider taking detailed measurements and creating a sketch or CAD model to aid in bracket design. If you lack fabrication skills, a local machine shop or welder could create the bracket for you based on your design or measurements.
