Thanks for the clarification on the fitting issue! Yeah the belt does help but I will also replace the straps, better to make two adjustments rather than relying on the canvas belt!
This is how it looks with the belt "thrown" in place:
From the front I'm concerned about the kidney plate sticking out a bit, I've seen people use ABS connections to align both parts properly so perhaps that will help me further on if the new and tightened straps don't solve it.
The back looks nice, need some fine tuning on the duct tape and the strapping of the three pieces but I feel I can pull it off easily.
The left side looks better, but it will still improve by replacing the straps attatched to the lower split rivets and perhaps the middle one too. This will also help keep the top corner from overlapping the ab plate and, if that isn't enough, use some ABS straps to align both pieces.
The right side also looks better, but It will also benefit from installing non-elastic straps and making them really tight.
