I have a set of R40 and R43 "Fall-Line" wheels.
These wheels are the "true" Fall-Line R43 version
Thanks for the clarification, these are the true fall-line R43's! I asked a friend and he said HRE can't bore them to fit center caps if you really wanted them, either way bump, really motivated to sell this week guys! All Pm's replied'
