Ok this doesn't really qualify as a "mod," ha. . .just a fastener change. . .but if you're anal like me, maybe this will be of interest to you..
I noticed the other week my 6 month old CT was developing rusty license plate bolts already. . . I already ditched the dealer plate frame, but I had carried over same fasteners.
So I put in some stainless steel button head fasteners in the correct sizes, which you can order from my favorite fastener place on the web, Fastenal, individually (i.e. not by the case) - which is very rare.
Front plate: 4 @ M6 x 12mm at $0.2041 ea
Rear plate (if you have a skinnier plate frame): 4 @ M6 x 16mm at $0.2514 ea
Rear plate (if you have a slightly thicker plate frame): 4 @ M6 x 20mm at $0.3116 ea
