Help removing windscreen and wheel inserts

[manaco986]

i am having trouble removing the windscreen..it seems like it shoud be easy ..i can get the levers to move but the screen wont pop out..i dont want to break anything..and i think i ought to leave it alone...also how easy is it to pop out the black porsche decals in the center of the wheels and replace them with colored porsche crest ???and what is the best to buy for the money????..i found a set for around $160
