I agree with Heath. Wait.
Color variations between lots used to be fairly common. The the workaround is to use the dissimilar colors ending in corners, at shadow lines, and the like. It's very effective in hiding it because light angle accounts for the bulk of the color perception. If you do choose to repaint to match, that trick can cut down on the amount of repainting you need to do.
And tell the mfr that the excuse of different run numbers pretty much faded out in the '80s/early '90s, at least in products that are similarly packaged. I haven't had that happen in decades. Today, everything is color-matched so even going to Home Depot for another can rarely results in a visible variation.
Very nice work on your truck, btw.
