There's been at least a few posts on this subject but I found that when I got the center gap as close as possible my windows no longer sealed to the t-top weatherstrip. I actually widened the gap and got a really good seal.

Trying to get the center gap closer...because the owner wants it that way...is NOT always the way the car was designed. Some Corvettes just will not allow this to happen while another Corvette will. I know this all too well.
Also..getting the T-top to the rear and the gap as close as possible is also something I would not do. But do as you wish.
FOR WHAT IT IS WORTH:
When I am setting up the gaps on a car I am restoring or painting....I get the gaps consistent so there is no gaps that are obviously wider and look out of place. This DOES NOT mean that ALL of the gaps are the exact same...but they are well with in a comfortable range that 'tricks' the eye and still makes the car look pleasing to the eye.
In 30+ years I have not yet had anyone say the gaps are not right...and those that do know me know I am really picky about gaps.

There are some variables that will somewhat dictate what you can do and what you can not do.
Your weatherstrip does play a part in this...or can cause for adjusting/alignment issues due to its density and 'fighting' against you trying to rotate the top and get it square.
The rear guide pin that goes into the center bar when you begin to install the top is what is going to cause for some issues (possibly) because getting the gaps where you want them is one thing...but also getting the T-top flush to the upper rear body area also is a major concern of mine and that is more important than the gap (within reason). Shimming these center guide pins and the sealing ability of the T-top w/strips and all that come into play.

Hi,
There are 4 locations that come into play when adjusting the roof panel's seals and gaps.
First, the pin in the front outer corner of the panel. It's two '12 point' bolts are used to adjust it.
Second, the adjustable 'wedge on the outer face of the halo. this wedge seats in the 'receiver in the rear corner of the roof panel. The wedge can be threaded in and out and it's location adjust by the 2 screws that hold it in place.
Third, the two 'tongues' that seat in receivers along the bar that runs from the windshield header to the halo. The tongues can be moved and also shimmed.
All these points must be loose to begin the roof panel positioning. There's information about the adjustment in the AIM, UPC 1 asm, Sheets F14, 15, 16.
Good Luck!
Regards,
Alan
Front outer corner. Note 2 bolts and nylon bushing for the pin.
One of the two tongues. Note the bolts and shims.
Wedge moves in and out an2 screws move the wedge's position.
