Chuck's car was also ordered with what is likely the ultimate performance option for the Boss 302: 4.30 gears with a Detroit Locker differential. Ironically, such a choice automatically bought the buyer an engine oil cooler, but just as with Chuck's Boss, such a ring-and-pinion didn't mandate a factory tach, instead, there's only on the 6,150-rpm rev limiter under the hood. Weird. Regardless, the digger rear ratio and hard-core diff could do wonders for a small-block Boss 302's straight-line performance, putting the high-winding mill in its sweet spot in nothing flat. Teamed with a close-ratio Top Loader and suspension that was as good as it got in the era, Chuck's Boss would be a potent competitor for most of Detroit's premier nameplates even if it were painted pink. Thankfully, this isn't a machine inspired by Mary Kay, so we can say with a straight face how much we love the combination: unusual, fast, loaded, and dripping with eye-candy. Who could ask for anything more?

Colors Of The Rainbow
As we alluded to, Boss 302 colors were extremely limited in 1969, when just four were offered. Such was not the case for 1970, with 16 of the 21 regular Mustang colors being readily available, along with many others by special order. Our curiosity sparked by Chuck Allen's rare pastel yellow, we decided to evaluate these cars on the basis of the most and least popular colors. Both Kevin Marti ( and The Boss 302 Registry ( were a great help in our quest for numbers, and we're grateful for their assistance.

Hands down, the most popular '70 Boss 302 topcoat was Bright Yellow (1,454), followed some distance behind by a close-knit group that included Calypso Coral (866), Grabber Blue (861), and Grabber Orange (832). The rarest production color shows as Bright Blue Metallic (1), followed by Yellow (4), and Dark Aqua Metallic (9). Of course, special paint orders likely yielded a number of "one of ones," but Ford's production data grouped special-order paints all together, of which there were 64 among the '70 Bosses.
