STR34

Hey guys, i have 1998 R34 GTT coupe and am just wondering if anyone knows anything about these altia/nismo rear spoilers. I have attached a video for you to see. The spoiler on the top is very loose and wobbly moving up and down and now is dislodged and scratching the paint when moving. Has anyone had this before or know if it can be adjusted or if the top part can come off? Thankyou for your help. 2D26A346-EB30-4C75-B1E9-B34D6B0A1D38.MOV
