Technical Header building tool

I am going to build my 2nd set of headers for my truck, and I am looking for a post on here but can't find it. It was about building a tool to help find the angle to cut the tube at. I'm sure there is a name of it but looked on the Google and couldn't find it there.

i believe it was a tech week post.

 

Its in the Speedway catalog......

 

If I knew the name of it I would look in speedway, but I don't. I have typed in everything I can think of to find it but no luck. I also believe it was in tech week. it was such a simple thing to make, just cant find it.
