Hey All; I'm getting ready to swap in the 10 bolt posi chevy rearend into my 73 Gremlin, and I need to get some air shocks so I can clear some big tires. Is there an air shock available that people have used with the stock rearend? I have extended shackles, but right now the stock shocks are extended all the way, and I'm getting a stiff ride. Thanks for any info. GaryB 73 Gremlin in Ca.
