By looking at a HELIX DP, is there any way of being able to tell whether it is a v1 or v2?

I have one that I bought for my last evo, but I don't remember if it was a v1 or v2. Now that I have an IX, i want to make sure I have the v2 before I go to install it.

 

The V2 has a bracket for the hangars that just slip on and off. The V1 is bolt on to the hangars.
