MNSmith, just to clarify I beleive there are two bolts accessed from inside under the dash (these I have installed) and one from the outside that I do not have installed.
Jon, I have moved the hood up and down with the spring arms disconnected in the process of adjusting the hood to cowl gap per Carl's procedure. I beleive the gap change I mentioned appears when I install the spring arms as they are pushing the hood when the hood is closed. I believe per Carl's procedure the first inside bolt is tightened prior to installing the spring arms and the second inside bolt is tightened after the spring arms are installed and the gap "adjusted". I have not seen much change to the gap when installing the spring arms initially but the gap seems to grow over time (not a lot) so perhaps the installation of the third bolt would help prevent that creep.
Carl, thank you for the offer. I have sent you a PM.
