hello, got a 5.4 4x4 97 expy, just thinking about when the air compressor finally dies, can you just replace all that complicated stuff with some good old coils? is there a mounting bracket for them? how hard would it be to convert once the compressor goes out? this would allow me to raise it to the height i want and just keep it there all the time,, just thinking about that and how much it will cost to get all that stuff working again
