Okay, I've scouted the literature and I am torn between whether the Tuff wheel was actually offered for an E-Body as a mid-year '71 option only, or whether there was another unknown wheel in mid-year that utilized the same horn cap.

The reason I ask, is that the Tuff wheel horn cap, #3575564 for A-Body and B-Body, is the same as 1972-74 E-Body two-spoke horn cap part numbers, but it's also listed for post-April 1971 E-Body to replace 4003 GX9 for the "BUTTON, Horn, w/o Rim Horn". (group 8-33-17 page 8-42 of the 70-71 parts catalog)

So because the standard Challenger and Barracuda steering wheels didn't utilize the same horn cap as the Tuff Wheel as far as I can tell, can anyone tell me what the mystical April-1971 optional steering wheel was for E-Body models?

I know at least one book says something about the S84 (Tuff) wheel being optional on 71 Cudas, but I cannot confirm this with the factory literature.


Many thanks!
