Thanks Guys.
Ok, got the upper piece of the gun cover in place, the gun cover is actually one large section so the way it has been done so ran a bead of superglue along it so it means plenty of careful sanding to fill along the sides to remove the join line, which it appears that I have nailed it....
plenty of reinforcing on the inside of the cowling to ensure all the pieces are set right and have a strong bond.
Also fitted the resin exhausts into each side of the cowl.
Added some Red lines to show where the join line is/was in the last pic.
