Started assembling the lower skins and muffler shroud.

Dimpled the bottom skins and riveted the com antenna doublers and skin stiffeners to them. I’m only installing a single com radio so I only drilled out the right side skin for the antenna. The left side I installed some rivets to fill the starter holes. I did install the left side antenna doubler in case i want to add another radio later. I can just drill out the rivets and upsize the holes to install another antenna.

 

Dimpled the muffler shroud parts. Riveted the doublers and muffler hanger brackets to the shroud sides. Riveted the nut plates to the fuel pump brackets and then riveted the brackets to the shroud ramp.
