Thanks for all the responses. You've made it clear that the crossmember needs to go between the frame rails so I will follow the advice. N2TRUX had a good point too. Putting it between the rails will open up more options for ride height, etc. later. I am currently not with the truck and am in Germany, so when I get back I can get more hands on. I am trying to get more of the theory straightened out now and will really delve into the project around Christmas time. These trucks are addicting. I'm on another continent and still thinking about it. Thanks for your help.
