Does anyone have a drawing for the two diagonal struts that go from the top of the front cabane struts to the top of the firewall
There struts are used to set the fore/aft position of the wing during weight and balance

I don’t believe there is any drawing for those struts. Everybody just makes them to fit their particular plane.
They really don’t so much set the wing location as the wing location dictates the struts lengths. Apparently they are there to prevent the wing from moving forward and trapping your passenger in a crash. Yours look like they are adjustable which is probably convenient. However, if read what William Wynn has to say about them, you’re actually better off welding them directly to the cabane struts.
