That's the ticket! But widened only with the right arrow direction - so the front face of that (now wider) support sits closer to the black intake like it is on the prop vehicle.
Is it possible to address the cut-outs on each side circled here? On the prop/build from the movie the rounded sections sweep - they're not semi-circles.

Not a huge deal, but a good catch, hopefully it's not too late to remedy that.
While closer shots are nice to see the often incredible detail, posting "flat" plan/front elevation/side elevation view pics as a project progresses (preferably with a couple of different 1/6 full figures as scale ref whenever possible) is key in catching this kind of thing early, as well as judging the overall proportions. Especially if those pics are taken from a ways-back with a slightly zoomed-in lens to further diminish distortion.
One issue with giving feedback with this unique (and I'd argue important) project has been that most pics have been closer angles that are often a bit distorted/canted so harder to pick out things like the semi-circle cut-outs or even any overall proportion issues that can be harder to fix further down the line.
