How In The World To Remove

[4oldsmobiles64]

Hey out there,
I've owned 8 AMC Vehicles and 88 Supreme Classic, 1979 Hurst Olds and now (keeping for myself) a 1980 442 real Vin# checks out as real.
I don't pretend to be a master mechanic and know all BUT
I need to remove my back interior kick panels and found 2 in a junkyard that is really in good shape.
How in the blank do you remove or feed the seat belts though the slot in those panels??????????
I can't figure it out!!!!!!
Thanks for anyone's input.

Make sure you got a T-50 torxs bit if the belts are in good shape, then feed the mount slide into the openning where the belt feed thru the lower panel at an angle. If the belts are shot, see above. If those belts are good & black pull them all.
