FettDad,
Don't have the pics readily available but here's how I did mine.
Using machined studs [same as the collar and backplate], screws and washers, I first drilled a hole thru both the cod and kidney plate at the sides after measuring.
And since Boba had a 'G-string' [I use this term loosely
], I glued on white elastic to the bottom of the cod and then had another elastic strap cut for the waist [this was done to give me a more comfortable form fit around the waist and some tension to hold up the cod piece and not worry about it sliding down
]. \
The white elastic strap was then looped over the waist strap at the back [for the G look.
] and the ends of the waist strap was hole punched to accommodate the screw and washer that will poke thru from the inside and allow the machined stud to screw on from the outside.
So, if you're looking from the a layered view, you will see, starting from the inside: Screw head, washer, waist elastic strap, kidney plate, cod piece and then machined stud.
Hope this helps somehow... I'll try to get pics later tonite...
Stay safe,
Tim.
