My thoughts on the Bow Pedal styles from the Original Stingrays I’ve owned in the past and the ones I currently have.
1) The Large caps with single arrows were used on the 1964 and 1965 Super Deluxe Stingrays.
2) The Small caps with the single arrow were used on the 1966 Super Deluxe and ‘66-‘67 Fastbacks.
3) The Large dome end with the crimps and double arrows were used on the 1968 - ‘70 Fastbacks and Krates.
As mentioned, there is always an overlap with most all components on these bikes.
Plus I’ve seen a few odd styles of caps over the years that may be an owner or dealer swap ??
