A closure panel arrangement is provided in which a closure panel 6 can only be retained when appropriately aligned with engagement between clasp hooks 8 and pins 9 is achieved along with association between latch hooks 10 and pins 11. If there is not appropriate association and alignment then a bias 12, 22, 32, 42 creates an outward bias force upon the closure panel 6 whereby the panel 6 will continue to fall out. In such circumstances, the panel 6 cannot remain in position due to simply key fit interference/friction association of sufficient strength for non-operational conditions but which will fail during operation due to vibration or stresses.
