it should be noted that i only want to replace my cruiser bars with the drop down bars from another bike. i guess i want to replace the "bike stem?" I still can't find easy instructions for that

also there are no bolts that hold the handlebars in place. the stem itself just encloses over them so it looks nearly impossible to replace without replacing the stem as well. is that usually true for cruisers?
