The fenderwells are cut out on this car for headers so I made a small patch panel to hold the coils. Not sure if I'm going this way or not but I might. It seems like it will work.

I also made a two piece cover for the heater hole. That way I could put a grommet in it and hold the bundle of cables for the EFI box. This seems like it will tidy things up and cover up the big hole in the firewall at the same time.
