Little bit more done this afternoon. Braced the chassis up at the back before I cut out the tubs along with the chassis. It attaches just above the old beam mounts on the chassis and then across at the rear. I could of put in a diagonal brace but it then seriously restricts my movements "in the hole". I doubt its gonna move anyway but I'd guess this would be enough to hold things were they should be.
Was also playing around with my manta hub & stub axle arrangement. I'm going to have to drill out the top and bottom wishbone mounts to remove the taper to fit RJs. Looking at the hubs the won't fit inside the centre of my wheels. There's literally only 1-2mm to come off but why did vaux make them different???
