Refurbishing the AC system on my 92. Staying with R12. I see folks recommending Integra and Legend units to save money or get a bit more capacity. I jumped the gun and purchased a legend unit and see it is not the right bolt pattern and will return it. So i need to go to school on my options as I also have a 3.2 swap in the works and hope to do this swap without touching the AC system. Any comments greatly appreciated!
