I had the identical issue with my old Miata.That thing never closed easily. In the beginning I had to hop onto the back of the car and push the top forward while someone closed it from inside the car. So I let it sit closed for weeks and weeks. And since it was only driven weekends it almost always sat in the closed position.
Nothing. A royal pain in the arse. And there were alignment issues to boot. Which got me thinking it has more to do with the looseness of the hardware on the frame (being a used car) coupled with a very stiff, right out of the box canvas. In other words I think the hardware becomes too loose for a top that is not going to be stretching anytime soon. And that's if the hardware on the frame can even be retightened to produce more stretching or if its like the annoying sun visor that won't stay up unless you simply buy a new visor.

I'm giving hard thought to just replacing the plastic again. Or lucking into an 03 OEM full top assembly which is a trick since most Boxster tops are not properly washed (detergent was used) nor Raggtopp protected (faded).
