Take a look at johnos build thread, I've done similar but no fancy bracket just drilled the grp bar and used a bit of studding.

I felt that bent Ali straps were to flimsey

Thanks everyone . I will go down the rivnut route! just hope the rear tub fis.

I know the book shows a tab bent over for the tank straps with a bolt through to the chassis but as soon as you tighten the thing up the tap will straighten out and not really tighten the tank down. If the method used on commercials was used it would be dead simple to re tighten at any time because you would only need to tighten the nuts from under the car. You would only need to weld the studding straight to the strap and there would be no tab trying to pull out straight. just thoughts

You could use 25 x 3mm flat bar around the tank and put 2 25x25 angle on the ends and bolt through,agricutrural but strong.:D
