how do you remove the trim on the windshield on a duster?

Well thank you...I watched a video on how to do a mustang and it did not uave gaskets like our abodies (cheap Ford's) and they used a block of wood to get some space between the window and shoved that red handled tool in though lol I was hoping someone would reply with away to make a tool or say something like you can use a clothes hanger lol
