I have looked through many threads and sites but can't find some specifications. Bssically, I have purchased a truck that I want to turn back into stock. It appears that the springs have been modified, but it is hard to tell. Can comeone with a stock truck help me with the following dimensions?

1. Bottom of frame rail, at the very front, to the ground.
2. Bottom of the fram rail, at the very back, to the ground. From what I have read, this should be about 20.5 inches.

I appreciate all of the help. Before I start I am trying to figure out what I actually have!
