I did not know that. Are they the shorter 70 Barracuda painted ones or the longer 71-2 Plymouth painted ones? Why were they just used on some Challengers? Seems like the ones that I've on Challengers were the chrome ones.
The part number in the parts book for a complete assembly is: 3420 727. That is the listing for 1970 "B"(all models), and 1970 "J" (all models except JH with 340. With JH 340 the part number is 2930 781 which I assume are the chrome capped ones, which is also the same number for 1970 Valiant cars. There is no specific listing for 1971 Challenger so it appears that the same information applies to 1971 cars. Which would include the 1971 J that I have.
