Alexzzz's info is incorrect.
The bolt pattern for the 3W 150 and DA 150 are exactly the same.
The bolt pattern for the 3W 150 is different from the 157/170.
The 3W157/170 is exactly the same.
Hope that helps.
Incorrect? That is strange; I have a 3W150, 2x 3W157 and a DA150, you want me to make pictures
