Alignment of Chassis roll bar plates
 

The big ones tacked to the top of the seatback rails. As they are not symmetrical
I assume the holes need to go to the outside furthest edge and nearer the rear of the car. If that makes sense, so the roll bar is wider and sits slightly further back than if I welded them the other way round (ie, less wideth on the roll bar and the hole nearer the seat back rail).

You want it to the the outer edge so the roll bar is as wide as the car

I could just look at appendix 1 in the book doh

Take care with the shock bracket on the roll bar mount too Mike,it is possible to place them wrong as the book is not clear .

dont think I'll fully weld the plate to the car until I have my shocks and rear bones/uprights to check alignment. I have fully welded the brackets to the plate and the nuts and the tube though.
The book seems fairly clear combination of the appendix diagram and another one that show the clocation of sus brackets give most of the dimensions!
