D1 And D2

[leroybrown911]

Hi

Can someone please help me, I have started to fit the diagonals to my chassis. However D1 and D2 dont look right. I know they will not line up perfectly with the uprights and top/bottom rails but I do not want any issues when fitting side panels.
Do I need to inset D1/2 so the allloy panel will fit flush between the upper/lower rails. Or do I line up the outside edge of D1/2 with the rails, if so, will the panel be shaped aroung the material that protrudes as a result of this?

Hope this makes sense to somebody
