But here's the thing... if it had to do in any way with a front vs rear distribution or weight/rating, wouldn't an alteration to the top whether ttops or astro be neutrally weighted due to where they are placed on the car, and where their weight distributes downwards on the frame with a roughly equal share of weight allocating to both front and rear "axle/members" as it were?

Your argument holds true if you use aluminum bumper supports or steel bumper supports front or rear just as well. They're about the same size, so they'd likely cancel each other out.
Total weight above the axles may be a consideration, we just don't know. I know it didn't alter the "computer selected" spring choice much either. I mean, really...95% of 1984 F41 cars came with PZ or SW rear springs, and AFA front springs. There may be others, but these are mostly the ones I've been seeing. Front/rear distribution may have been a factor, but why some had just a front steel and rear aluminum, when others had both the same? I dunno. An odd thing in my small sampling I've seen is that I haven't seen a VD6 without a VD7. Although they did use VD7 without a VD6.
So top option or no top option, it didn't seem to sway the choice of aluminum bars or steel bars by those options alone. So it had to be something else.
Maybe it was some engineer who smoked a little too much of the green stuff. 🙂 Knowing someday we'd be scratching our heads trying to figure out why GM did something the way they did...
My 84 came without G80. My 85 442 has G80. My old gray 85 442 had peg leg. All with front/rear aluminum. Nope. Doesn't seem to correlate. WTF GM?
Yeah I thought I knew everything as a kid going racing!!!!! I'm a drag racer, and growing up racing I tried a lot of different things and I wasted A LOT of money. I admit I tried the flavor of the month magazine dyno parts based on all the claims because I believed I needed them. All I found was they just didn't work at all. Working at an engine builder during this time, I even saw a lot of dyno gains that didn't amount to anything in ET in the car. There were quite a few times the car didn't run the numbers I THOUGHT I was going to. I can tell you how one time I spent a couple 1000, and slowed the car down .15 from a 9.32 to a 9.48. I know I sound grumpy but when somebody tells me that they put parts on that I KNOW only amount to an 8-10 hp gain and they can FEEL an instant difference I just say wow, that's great. I dynoed my 548 inch motor and worked for 23 hp on the dyno. In the car, it went from 9.089 to 9.03. But hey, if you want to spend 100's of dollars on a part that showed 6-10 hp gain in a dyno test, go for it. On the street, it will show nothing and I learned a lot of stuff the HARD way. I don't claim to know everything, but what I do know was learned by wasting money and breaking parts.
My 81 was in great shape overall, with a good vinyl top on it. I pulled it off anyway, and it was just starting to rust.
After joining this site I noticed that while I had a factory landau top, I didn’t have landau pillars. Not sure if they stopped the landau b pillars by 81.
I used to think a McRib was an actual pork product and safe to eat.
I too, know better now.
They did use the B pillar trim on Landau cars in '81. What you had was the cabriolet vinyl top which is the same but with out the Landau trim/RPO.
