Nice!
Yah that looks similar to the model I used. I downloaded a 2-d cad version (I am not saying that it is the same as this one but the way the head is radiused and the level of detail is the same.
Point is that the mounts were way off. I just suggest that you double check some mount measurements if you are trying to use them for actual locations. I found the head mounts (which aren't symetrical to be "twisted" from each other by 3/8" around 7 degrees, and the rear mounts were 3/16" off in separation.
