Chassis
Both coupes are identical-literally-under the skin. Both started as rust-free cars bought in California, with Roy Brizio Street Rods tackling the modifications to the stock frames, adding tubular crossmembers. Heidts Mustang II independent front ends went under both, with QA1 shocks, Heidts antiroll bars, GM 11-inch brakes operated via Pete & Jakes pedal assemblies, with Corvette master cylinders and 7-inch boosters. Identical 3.7:1 limited-slip 9-inch Ford axles were hung on Chassis Engineering parallel leaf springs in the rear.

Drivetrain
Brizio had a lot of positive results using Ford crate motors, and with the only stipulation that the coupes remain Ford-in-a-Ford, opted to install Ford SVO Racing 351 motors in each car, backed by Tremec five-speed transmissions equipped with Hurst shifters. Walker radiators found their way into each engine compartment, while the 2 1/4-inch exhausts were fabricated in-house at Brizio's.

Wheels & Tires
Gennie steelies from Wheel Vintiques were used on each Ford, 15x6 in front and 15x7 out back, ensconced in 205/65-15 and 235/75-15 Goodyear rubber respectively. One of only five differences between the cars' spec, not including the body styles, is the year-specific hubcaps on each, coupled with trim rings.

Body & Paint
Both coupes are bodily stock, and both were painted by Jason Haskins in Sacramento using DuPont paint, with Peter's '40 in Boxer Blue and Franklin's '46 in black. Sherm's Custom Plating, also in Sacramento, handled the chrome work on each car, while identical swan neck mirrors were fitted to each.

Interior
The fourth difference between the two after body style, color, and hubcaps is the choice of steering wheels; Franklin going for a LeCarra item and Peter opting for a Juliano's wheel. Other than that, both cockpits feature Vintage Air A/C, Auto Meter gauges, ididit columns, Wise Guys seats, wool carpet and upholstery by Barry Ward, with ox blood leather in Peter's and black leather in Franklin's.
