I started the modification of the 216 side cover for the 235 I have in my 37,I will put it over the existing 235 cover and cut out around the plugs and had to cut out more around the distributor and road draft tube. Since there is a outward dimple on the 235 cover I heated the 216 cover up and made one on the 216 cover so it would fit better,tomorrow I will weld some nuts on the back of the 216 cover so I can bolt the coil bracket to it. I have taken pics so when done I will post them.
