Over the past few days I've been slowly working on the lower cowling, trimming (sometimes as little as a 1/64" at a time), sanding, over and over and over again. At this point I now have an excellent fit between the front and back of the upper and lower cowlings although the lower cowl still needs to have the aft end trimmed to allow for the paint, about .025 inches. Once that's done the lower cowling (fore to aft) will need to be sanded to match the upper cowling for the Skybolt fasteners. Also, the aft hinges, lower Skybolts, the oil door as well as the 4 plate nuts on the nose pieces still remain. However. there is light at the end of the tunnel and it's not an oncoming speeding train.
