I'm done installing the new firewal on the E-Chippy, I will post pictures tonight after work by midnight.
It came out good as I used the original one as a guide ( pictures will show in detail ) with this now the prop washer is flush with the cowl and not forward from it, the prop is just infront of the cowl ( looks really good this way ) I end up gluing the new firewal 1/2" bihind the original one ( as predicted ) using it to guide me for the correct position for the new firewall and using the 1/2" spacer was a great idea and made things very easy to instal
