Hey guys, looks for two measurements off the front of the frame rails on a 55-57 3100 for my current build. 1. The height from the bottom of the frame rail to the top of the body clip mount (bracket attached to the top of the frame up front). 2. Length from leaf spring hanger (front of front hole) to the front of the frame. I started with a ch***is that had an F body front clip and I'm now finishing the length for my porterbuilt replacement. Thank you for any ***istance.
