To bolt the wing to the BP, I use either 1 1/4 (part #93180A325) or 1 1/2 (part # 93180A330) "316" SS carriage bolts with either these DSS delrin nuts or the Oxycheq speednuts.
It also helps to have the little plastic retaining washers (part #91755A230) that hold the bolt in place which makes it a lot easier to get the bolts through the STA/Wing/BP and it then holds the square part of the carriage bolt in the square hole of the STA which makes it easy to tighten the nuts. I take mine apart every dive to clean so it makes things easier.
