I run one my 360 with an A500 behind it. Works ok. Bracket is a little flimsy, and I had to add another spring down on the trans, but can't remember why. Also, the trans bracket hit my trans tunnel. I will be making a better fitting one later. For now, I just bent the stock one.

You will want to pull some tension on it, and then drive it to see where it shifts. More tension, higher shift point. Pretty simple.
