Once the backplate adaptor was fitted to the shell, I needed to assemble the unit, it went together OK, but things went in a little differently.
The Wing I was going to use was an Agir Brokk, It fitted nicely as the backplate adaptor needs a larger distance between the bolts so as to allow the lungs to expand. Note that some Wings will require an extra eyelet placed in the fabric. The Agir wing has 3 eyelets at the top and 3 at the bottom to allow a normal wing to adjust on a backplate When using the adaptor The Agir uses the eyelets furthest from each other.
The harness was a Transplate Harness from Diverite with their weight pouches fitted. I bought this when I first got the Agir Wing as I never got on with the one piece webbing harness.
