I also was able to remove all the zip ties that were holding the wire bundles in the Firewall forward compartment.. There are a few heat resistant ones that are holding some hoses and tubes etc.. that will remain.. But for the most part I replaced everything firewall forward by tieing up all the bundles with waxed lacing cord.
Since I was back to working on the firewall forward I torqued all the remaining items an started riveting in the baffle rubber material. It went in easier than I thought since I had already pre-drilled it with the baffles before final assembly. For the most part except for some odds and ends I am finished with the firewall forward.
