valve stem caps?

other than that, i would imagine some nuts and or bolts may carry pre 36 part numbers.

John- not sure about the valve caps ? that's possible..

Curt- twin cams have NO timing hole plug.

answer: The Push rod tube springs, & caps are the oldest carry over parts still used today. HD part # 17947-36 & 17945-36B

old parts

The oldest carry over part that is possibly still used on H-D's is the Schrader valve stem. (if the Davidson Money Company still even uses American tires and tubes,which they probably don't) The valve stem caps were nickel plated brass from 1903 to 1959 (except the 5.00x 16" inner tubes which I think came out in
'40.
