I thought show cars were for show and transportation cars were for transportation...it is illegal in Texas to even be parked without the front plate. It is not a moving violation, it is a display of registration issue.
One could simply use a sharpie to do it, typically if something is "changed" to the point of ruining a piece of equipment, especially a piece that you are used to installing, its rather obvious that isn't where you had it.
it'll fit, i've been around the same amps with the same size 4g, sometimes with cca which is typically a bit larger than copper 4g and i made it work, you have to twist it a bit and push....
it'll work, get to it.
