One would think...but these weren't ever used....makes me wonder if the chemical compound wasn't right before they poured it. I've seen worse older boxes that were way worse than this and they still work. I got one Mopar one that is from the 80's that came on/off my RC when it was new(I think) that is way bad/nasty/worst looking on the back and still works. I'll be doing a short video of it(them) on my run stand that has an early short deck Dodge Hemi on here soon I hope with all these being tested.
