That looks good to me. CS Weapon VC Hud3d in the Acceleration F/A-18.
Bit tricky, how I did it:
I read this forum, lots of clues and some big pointers!

1. Aircraft.CFG change eye point to:
[Views]
eyepoint = -17.0, 0.0, 3.38    //-17.0, 0.0, 3.5

Had to, just was not looking at the cal. circle through the hud.
Captain Sims eyepoint is -17.0, 0.0, 3.358.

2.CSWeapon.XML change under <GaugeInfo>-in FA-18 folder:
<CollimationData>0.0,14.40,3.38,0.310</CollimationData>

"Do not edit while F/A-18 is loaded in FSX"
notepad!

3.In FA-18 folder\panel.csweapon\Panel.CFG change:
[Vcockpit01]
//gauge03=fa-18!MFD, 578, 579, 440, 440, 4 NOSCANLINES     // Original F/A-18 Hud !!! NO DELETE(//)
gauge03=CSWeapon!hud3d, 569.8, 523, 462, 500, 4 NOSCANLINES    // CS Weapon VC hud3d !!!width, height, hor. size, vert. size (all in pixels)

Thanks for all the help! I'll upload it to Captain Sim as a mod for the Weapon. 

Can anyone test this? And let me know, my landing gear has a fix so my contact points are different from stock. But I don't think it matters.
