bike

I'm trying to fit the bike rack in the pictures through drywall. I bought some nice long drywall screws as shown in the pic. The problem is the gap in between the drywall and the wall behind is too small to fit them. I'm not sure what my best options are here but ideally i will have my bike...

I need a longer length of the track in the picture, but I have no idea what’s it’s called in the trade nor what to search for. could anyone advise of it’s name, where I might be able to get some? It’s for a bike carrier, my MTB is XL and is a bit dodgy during travel. Thanks.
