Hose connector holes

Just got my order from Toolsand talent props. I got the double connector two pin hose. I’m trying to swap out the stock plastic piece from the pack and I can’t get the cnlinko piece in, the screw holes are all closer in than the pack piece. The 2nd screw is tough to get in and there’s no way to get the 3 rd and 4th. The guy from Ghostbusters news installed the same piece on his but didn’t say there was a problem. Any tips would be great.

Used a different connector, but had the same problem. Just put the screws in at a bit of an angle, and then tightened them maybe four rotations at a time on each corner. It was stressful but it worked out.
