JB Weld plastic, some cardboard shaped like the console, taped to the underneath side of the console. Paint the JB weld over the cardboard the same thickness as the console. Then sand it smooth and I usually use the textured spray paint from Lowe’s to paint it.
I did the same thing on my purple dart and it has held up great the past 6 years.
Haven’t worked in the swinger since we moved here… got a huge parts score a couple weeks ago though…
