He was out of Omaha Nebraska area. Worked for Pontiac from sometime in the early 60's through the mid 70's. The only man I know that could strip down an engine while wearing white coveralls and not get a drop of oil on them. Don't know how he did that. I can't lift the hood without getting covered with grit and grime

You said your Uncle worked for Pontiac, I assume in the Atlanta area? If so what was his name as I worked for PMD from Oct. 1967-June 1987 and at one time used to call on the Atlanta Zone Office.
