lots of guys used to run these.. http://www.speedwaymotors.com/Garage-Sale-Mopar-Shock-Extensions,5614.html

I think those are a bad idea/kludge. You may have issues with compression travel. You need a shock with travel to match your suspension at both extremes - full compression and extension. Anything else is liable to cause problems.
