What are the dimensions of small flange?


I searched.........and I now know that the LARGE flange mounting hole dimensions are.........
60mm x 60 mm, (2.362" X 2.362") center to center
85mm, (3.346") diagonally

But what are the dimensions of the small flange?
Also what years were the small and LARGE used respectively?

 The small flanges had 2 different versions, the SJ410 and Sammy version. The large pattern started in 89 or 90. It's the same flange that is used in the kick. I don't have any handy to give you dimensions. Hope that helps.
