can someone tell me how to disassembly the deluxe seat belt buckel, so I can clean it get it to move freely and replace the belt? Thanks,

heres how i did mine-on back side where the stainless metal folds over i gently pried with screwdriver-bent up to be exact-then slid that top part forward -needs slight force- after that all comes apart easily. after reassembly used rubber or plastic hammer to bend tab straight.
