Hi yea I grabed a fist full of bolts yesterday from the foot well think I have a silver bolt a bout that size.
The strip is easy to remove just the four little black plugs two at each end. The rest is stuck with butyl tape not sure where you will get that. If you can't get tape you should be able to get butyl mastic in a silicone type tube in a motor factors. We used it fitting windows in houses in the past the only diffrence between it and silicone is it remains tacky like blue tack for ever you will see what I mean when you are removing your own one.
Here is a link not much info in it but might help
