Quote: My old R/T SE has a SPD of 723 & does not have the dimples... I guess it's suspect.....
I was trying to point out that there is some rhyme/reason and/or pattern to the dimple vs. no-dimple. The "maybe" period could be the last 3 months of the year. Your "former" car could be the lone exception for the end of July '70, or the last month of production might all be without.
My 702 SPD '70 Challenger R/T was finished at least 2 weeks late. It has many '71 attributes. My 801 SPD '71 Barracuda was assembled at least 2 months early. It has many '70 attributes.
