Molded inside the top is a metal plate that holds both the upper torx bolts. Use heat (MAP if you have it) and apply right on the torx bolt for a few seconds, pull away, wait a few seconds and do it again...and again. If you bubble the paint, you held it to long.This cycles the heat down through the bolt. The paint may darken, but most of the time I don't damage the paint if it is seasoned. Keep the flame away from the top..just close on the bolt. Use a quality torx bit and after the last heat up, quickly tap it in to fully seat the bit. Push in straight and hard as you turn and 9 to of 10 times, the heat will free it. I have removed 1000s (over 19 years) of torx bolts and only had to drill about 11 of them total. Heat works most of the time.
As a side note..
The key to the lower windshield/upper door hinges is apply heat to the inside hex nuts and just hold the outer torx while you use a ratchet/socket on the inside nuts.
