Welcome Noob. Sounds like you got deep pockets and a lot of work ahead of you. And if your pockets are really deep go with the orbits instead of the skyjacker. You will be much happier. As for you fiberglass, You might want to think of an exo to protect them depending on how serious you get, but then again you said its a DD . And worse case if you do your lift without duals in you might have to do your front driveline. That should only run about $50.00 at a shop. Well keep us posted and have fun
