I didn't drive yet then. Did the dock. I saw mostly BRIGADIERS.If i spelled that correctly. GM mfg. ?Double Diamond was rid of the old DF 860s with the 471 Detroits, when you arrived on scene
We ran 860s with high HP 671s and hydramatic trans. (note High HP)
Akers Motor lines were also in the way with their 4 bangers.
I think you had crackerboxes with 671s.
This was in Charl,1955, McLean was next door.
