Re: 1937 115 vs 1938 six distributor

According to the 37 and 38 model introduction specs in the service letters the same Delco dist was used on both years but there are a few very minor detail changes. Timing spec is different and point gap is different. Wonder if they might have changed the gap to open the points more or longer for a bit better spark and maybe changed the weight or springs for a different centrifugal advance curve. For having the same part number on the basic dist doubt there is much more they would have changed without going to a new number. Is it the Delco number you found to be different or the Packard part number? With such minor differences I would think the dists would be interchangeable.
