Sorry to bring this up again but I am finally getting ready to start welding the cab mounts and I wanted to be sure I understand what you are saying. I have looked at mine and I have a cab mount, the s-10 mount on top of that and this all bolts into the channel that is part of the cab. You said that your body is about 4" off frame. Does this mean that the cab floor is 4" above the top of the frame? Is this the cab mount height from top of frame to top of mount? Bottom of channel to top of frame?

Maybe another way of asking is to see where the bottom of the running boards are in comparison to the bottom of the flat part of the frame..

Hopefully I am making sense...

The reason I am so concerned is because I am hoping to have the running boards 5.5" above the ground when all is said and done. I have 2" drop spindles and 3" blocks in the back. The way the frame sits right now (no engine, no cab, no bed) is pretty high and I am wondering how much this will go down once all of this weight is on it.
