<BR>
<BR>I had my engine hung from the ceiling and mounted to the "engine mount" and I <BR>used a piece of 1/8 inch plexiglass (window replacement material from the <BR>local hardware store), cut in the shape of the firewall with the engine mount <BR>to firewall holes drilled in it, as a template. I could then hang the <BR>template on the mount and place various parts, drill mounting holes and also <BR>see what was going on from the cockpit side of the firewall. Ultimately, <BR>this became the template for drilling holes in the stainless steel and the <BR>firewall using the engine mount holes for registration. Once this was done, <BR>I placed nutplates on the firewall so that components and brackets would be <BR>removeable without taking off the forward deck.
