Need some info on ride height for the 49 GMC. I bought this truck as a stalled project. It was a frame off when I got it.
Looking to install a Helix IFS before I start the assembly so I'm starting with the naked frame. My issue is I don't know and can't find the factory ride height of the truck. I need to know the dimension from the ground up to the frame at some known point. Such as the height to the running boards or the height to the bottom of the frame just behind the front wheels or the height to the bottom (or top)of the frame at the very front tip of the frame.

Any dimension would be helpful or point me in the direction where I can find it.
