No instrumentation other than the odometer and gas gauge! I get 70+ MPG by coasting and going slow. I cruise at about 45 MPH with the engine spinning at about 1300 RPM.
The grill block is made from the bedliner of a pickup truck. Anything will work, but I like the look and it's virtually indestructible. I just cut two pieces to fit and used stainless steel screws to hold it in place. The center of the grill is open and I use the license plate to cover that. I have multiple screw holes for the plate and I move it based on ambient temps.
