Thanks for the info, learning every day!
So what generated the vacuum? Not come across anything on the various drawing and photo's that indicates a vacuum generator on the truck, so was a vacuum generated as a by-product of the engine to power the motor?
Tony, I hope it's a simple bracket, I'm not looking for complicated, I like simple. But more importantly I love accuracy and details! In the period photo with the arrow you can see what looks like a lip on the bracket. This could just be something in the background 'photo-bombing' the image. Looking at other components they are as simple as possible, so it's most likely a simple flat bar with 3 holes, just seeking confirmation.
