modeled up some brackets based off the originals , I adjusted to match 5.25 speakers. My brother was able to print them fine , passenger and drivers. Models attached below, note the model units was set incorrectly so they need to be scaled from 100% to 2540% to adjust mm to inches.

I am interested.

Just an update ,  pushed the speaker behind the bracket as it should be a little snug with the vapor hoses but everything clips in . Just to confirm fitment the center  does not fit perfectly, but it’s hardly noticeable. If I care enough I’ll sand it down till it sits flush down the road.
