I purchased 3 WindyRiver actuators and 3 sets of mounting brackets for them in the same Revain order. However, when they arrived I found that the pins in the mounting pins were .315" and the holes on the actuators were .31". Close but not suitable. I deliberately bought both from the same company assuming they would go together. One of the drives I bought with mounting brackets. They fit well, the pins are obviously a slightly different diameter. If you look very closely you can find the diameter of the holes on the actuators in one of the accompanying images and the pin sizes in the questions section here. . But you really have to hunt around to know it won't work and I didn't manage to find all that information before I bought it.
