A-Body door handle question

[nz383man]

All the repo door handles seem to be advertised as 67 or 68 to 70 or 71 to 76, what is the difference?
I want to put a set of the black button ones 68-69 on my 72 Duster drag car.

Beyond the chrome or black buttons, there is a difference in the way they attach to the latch linkage. Many owners have transferred those bits from one type to the other. Easy to do if you have both types in hand. Another member may provide pics of the 2 types. I dint have.

Thanks, I'm an Engineer so I should handle changing the linkage over, so new handles with black buttons it is!
