I wanted to provide some insight gained from hours of work and cuts, bleeding, bruises etc..

.
This truly had me stumped and I wasn't sure it could actually come apart without true carnage. After a lot of head scratching last night pondered, meditated today while working (not on this but actually working to make a living lol). Anyways a thought struck me, what if the whole contraption is carefully seperated from the foam core? That's actually how it really works! The fabric, release handle/paddle, bezel, metal bucket-ish looking thing all gently pry through the foam. I've included some pic's of the stuff.
I can tell ya this was a difficult task changing the back uppers (seat backs rear) from fabric to leather. There are a tremendous amount of hidden Christmas trees and snaps, screws and wierd funky things to deal with. About 10 hours just to swap fabric for leather. May be 3 more for removing the whole assembly from H3 and reinstall the whole contraption. Any way pic's.
After you remove the complete deal when you flip it over you'll see to tangs. Depress those with a flat blade screw driver and gently jiggle the paddle/handle to help the bezel free it's self from the underlying structure. This is shown in the pic's. There is a different kind of thing opposite of the two tangs which slot behind the paddle into the hinge area. The material is sandwiched between this section. Reverse this precisely to put it back together. This is way harder than it sounds.
