Not to mess anything up but you may want to double check that. I believe from the pic that is a 71 & 72 bumper mount not 1970.
Cool. I took the pics at the beginning of that post and added the years according to Duane. I also added to that post a pic of the ones I pulled within the last week off my low mile GSX. Its really hard to know what is and isn't correct but according to what others have posted what you have is correct for 1970.
