Since modernity was a primary goal here, the chassis also received a bit of attention. How's that for gross understatement? Chassis rigidity was assured with a custom tubular subframe connection system. Both ends of the wheelbase now utilize full coil-over-shock setups from Total Control Products, the rear employing the company's hugely adjustable pushrod arrangement that brings along its own subframe structure, three-bar axle control with torque arm; horizontally mounted Watt's link, and an FAB9 9-inch axle housing. TCP also supplied the power steering rack that is linked to a Flaming River column and tilt steering assembly. Braking is nothing less than a custom Brembo system having a 14-inch rotor diameter on the nose, 13 inches at the tail. And the whole belly is carefully finished in contrasting red and silver, just like on top.

Which pretty much brings us to the two-seat interior; actually, there is a sort of padded bench area in back but, seeing that it's literally surrounded by strikingly large Clarion amps and subwoofers, we'd have to guess it wasn't designed with passengers in mind-at least not sane ones. Up front, however, are nice comfortable Procar buckets, custom upholstered in leather by Tack Upholstery, who also did the door panels and other interior skinning, which no doubt consumed a couple cows' worth of hides. Even the dash pad is now leather-skinned, and the overall cabin theme is nothing if not modern. It may be a little thing, but we like the engine-start button on the console. "God is in the details," as the saying goes.

All told, the conversion from 351-powered Mach 1 to big-block Xtreme Mach consumed some 14 months and untold thousands of dollars. Now that it's done, Don is thoroughly enjoying it, but is probably already planning his next modernized Mustang makeover. Our cameras will be waiting.
