Thanks guys....the pics are most helpful. As it turns out, I went ahead and ordered a top from GMI just today, 6' long 3 bow, 79"-84" wide, 40"-46" high with SS hardware (they actually shipped it today as well

). I ordered their rear support struts which adjust from 28" to 40 something. From what I have found (and now your pics) FW's stock Bimini has the extended longer rear struts which fold up and and are captured by the nylon dealies when the bimini is lowered, with the short struts as a separate item which then hold it proud of the cockpit cover.
My plan is to rig up some short struts as a separate item to the standard GMI set-up. Would be great to find those plastic "holders" for the longer rear struts somewhere. Someone's gotta have them but I haven't been able to find them yet.
Any links for those would be appreciated, and again, thanks for the visuals! As a first time boat owner, this is all new to me.
