Squeeze and hold the spring loaded release and slide the entire clamp up towards the roof. They can be tough to slide sometimes but they'll go. Remove the 4 nuts and washers (2 on either side) and back off the bolts until they just clear the windshield bracket mount holes. You don't need to completely remove the bolts. I slotted the bracket mount holes in mine and used a couple of washers on either side of the bracket so I can just loosen the nuts to remove the windshield. Pull out the windshield at the bottom and allow it to slide down a bit to disengage the upper seal. Use a towel or something to protect your paint on the hood and fenders. The lower corners of the windshield can do some damage if allowed to contact the paint.

 

I used a dremel on the points of the parts that go around the roll bar on the windshield side to allow it off an on a bit easier, this was after I broker the windshield forcing it off.

 

I'll have to look at what you used the Dremel on. I got the inside clamps off, but have not tried pulling the rest of the windshield yet.

 

Here is a look at the parts that I dremeled.
