1966/'69 A100 Twins Build
Jim, do yourself a big favour and follow what I did to the doghouse recently. Instead of all those bolts and nuts on the two side panels, install some Rivnuts. That will make accessing the plugs and engine so much faster in future. I used 5/16" aluminium rivnuts, and the drill size for the square holes is so close, only a small skim comes off. I also bought some new SEMS bolts to make a nicer finish.
Pics below of the rivnuts in place. BTW - (for both side panels) the front top stud can stay - as it is easy to access even when the engine is hot. Also - the bottom front hole for a bolt will probably just need a tap run through it - already has a captive nut for 5/16" UNC.
