Hey, I'm jealous of your 'tintop', they're cool... & prolly have lots fewer leak problems... mine was leaking, a little at teh door seals. When I checked under the carpet, it became obvious it had been leaking for a long time. Now I have another repair project on my list.
I thought my top was OEM, but while I was fixing it's rattles I found a sticker that says "FleetAir"... now I know why I couldn't find the rear window supports. I'm hoping they're still available, unlike Bestop parts... which is lame being they were the OEM supplier.
I don't have my pics loaded on this comp, but here's a link to pics of mine. Again it's a FleetAir & attaches with four 'knobbed' bolts inside, to brackets that are mounted on the lip of the rear.

The rear window works just like a pickup cap, with 't-bar' handle & latches. I really like the tinted/slider rear windows, they have screen on them even... woot!! I wish it had the cool & handy roof rails that some have though.
After getting my Tracker & I bothered to notice, I've seen at least 4 or 5 different styles of convertible hardtop around.
IIRC Rocky Road still sells new hardtops... they're pricey ofc. I see them for sale used pretty often too, so you still have lots of options. IMHO they're a big improvement over softop.
On a side note, mine was MAJORLY rattley when I got it... & I HATE rattles. I used vacuum caps on the ends of the bars & some heavy waxed string on the t-bar joints like a bushing. (Just wrapped it around & tied it on.) Shut it up good... then I noticed how much my tailgate was rattling. I tried to adjust the striker, used an impact driver & PB Blaster on the screws & all... & couldn't get them to budge. Then I noticed that the rubber ring below the latch on the gate itself is on an eccentic. I turned that +/- 20* or so... & YAY no more tailgate rattle, even with the heavier spare on it!! It hangs up just a little... takes a slight *tug* to open, & a little more*swing* to close fully, but not bad & IT"S NOT RATTLING!! YAY!!

Heh, anyhow that's M2C.
