Hey Jay, you can tell pretty easily by measuring from the frame tube to the bolt centre. That is the critical distance and you would set it in position by running a (threaded) rod through the remaining three brackets and into the bracket you are replacing. It's now fitted relative to the other three the last dimension you need is the spacing between set with washers or a bush or similar. I believe they are the same, if you need pictures or help let us know.
