Roll Bar + Chassis Plate Help

[Tatey]

I'm at the stage of welding the roll bar to the roll bar mounting plates, i've fettled the roll bar down so it now sits level on the plates, however when placed on the chassis the roll bar does not sit in the middle of the 2 plates, it is sitting more on the outside of the plate, i've attached a drawing to show you what i mean:



The roll bar sits approximately 17.5mm from the outer edge of each side of the chassis. How has everyone else tackled this problem? Have you just fettled down the roll bar until it sits in the middle of the plate? Or have you just left it like that?

Also with the triangular chassis plate for the roll bar box thing, one side is 121mm and the other is 125mm, which side goes against cp3 and cp4? Is it the shorter 121mm side and the 125mm side goes vertically down? Depending on which way it is positions the angle it points at will change.

Cheers
