POL Hydroboost identification

[forestb]

I bought a Hydroboost from POL and I am trying to figure what year make and model it is from. I called them and they do not have that information. But they gave me the number of the people that do there builds an they told me that the people that would know that are out of the country for a month. I was wondering if anyone knows what year make and model they use.

What is the actual question about this part? Why do you need to know its actual application?

The reason I would like to know is because I need to buy a rebuild kit that includes The star shaped piece in the photo and the spring that goes behind it. I made the foolish mistake of hooking all the lines up, starting up my motor and pushing on the break without the master cylinder attached. The rod, the spring and the retainer and guide all popped out and I was only able to find the rod. The rest of the parts went to that magical place that all parts go to when you drop them while working on your truck. I might not actually need to know because it looks like there are only 2 bore sizes and I found a kit that comes with all the parts needed for both. I am going to look harder for my old parts this weekend.

Here is a link to what I bought.

I am certain that there is a pile of small nuts and bolts sitting next to all of my missing socks.
