Jim : you dug-up a gold mine on that one !!
The image below, seen in the 'old thread' you had linked us to, is an image I've long had on my own computer. I simply couldn't find it earlier in this current thread of ours, although I was looking for it :
Someone within the 'old thread' stated : "Golf Kart? anyone?" when referring to the image immediately above. But if we think about it, a golf cart is a highly desired, utility-type, open-aired vehicle; that when it becomes raining or cold, a curtain is literally strapped on - and life for the user carries on.
More than one person, in the 'old thread,' seemed to be really digging this rig (immediately above). Incidentally, the way I'm planning mine, with the Aircraft Green paint, the result will be similar, but merely a different hue of OD. I can't see how it won't look overly cool, for what I intend mine to be : a really, really nicely made-to-perfection trail rig (perhaps along the lines of the tan one of
@jim land ).
I suppose one could say this concept (with just the fiberglass cap) is really no different than Marshall's bimini top (which to me, really does look good) :
But with either (fiberglass or fabric), one could easily & quickly remove the upper top and go completely topless. It wouldn't be difficult. With the fabric, one could do this out in the field, and fold-up the top and place it into a container.
Not so with with the fiberglass cap route. But with the fiberglass cap, one could continue to have mounted compartments or lights or whatnot attached to the underside of the rigid top, that they would not which to remove. Plus, the fact of insulation properties from the sun & its UV heat. The cap is naturally white, and one can further insulate its underside. Its appearance is also of course uniquely different than what we'd see on a common Jeep. Therefore, the fiberglass cap remains attractive, both utility-wise & aesthetic-wise, to many of us.
And then, if it rains on us, while out in the field, we simply install (or roll-down) the packed-with-us curtains, as exemplified in the image immediately below (as extracted from the 'old thread.') :
This may look tacky to some of us here, but to others here, it doesn't. The reason being, at least to me, a 40-series Land Cruiser (like that of a golf cart mentioned above), as classic as it has become, is really nothing less than a pure UTILITY device. A 'utility device' being defined as "modifying it (or not modifying it...if one knowingly wishes to near-term resell) to however it suits one's needs BEST." Just like a farming tractor. And we've definitely seen that with golf carts; where, we now see ATV type golf carts, called "Gators" or "Big Reds," etc. And on them, just like a golf cart, one simply straps a 'curtain' around it when the weather becomes undesirable or inclement.
My concept of the roll-up window hard top is much like that presented in the image immediately above, but merely retains the two OEM hardtop sides, providing a greater sense of overall rigidity to the fiberglass cap.
