Looks like a fairly standard-optioned car for the southwest - A/C, and not much more. White paint, standard ginger interior, no Ram Air, Mach 1 package.
The good thing is that you can pretty much do what you want with the car - it's 'just' an H-Code (351C-2V), which is the second lowest power-output engine. The 3.00:1 rear gears and FMX behind 245hp make for a good 'cruizing' car (you're not going to smoke anybody off the line with those rear gears).
Those Magnums are most likely added-on by a previous owner, since they're not called out on the Marti Report - the car most likely came with Corporate caps & rings ("dog dish" hubcaps). Check the doors and upper rocker panel area for mounting holes/pins for rocker molding. If there are none, then your car might've had the hockey stripes - or, they could've been filled in as the car went into primer. Either way, you're at the point of deciding your own fate regarding adding options and additional items.
Now, you need to decide what you want to do with it. Do you want a faithfully restored car, or a restomod customized to your liking, or something in between? That decision will guide your way toward reassembly. If you plan on showing the car at Mustang Club of America events and competing for MCA awards, I believe you can have any/all factory options on the car, whether they came so equipped or not, depending on which category you choose to compete in. If you just want a cool car and have something specific in mind, the sky's the limit.
I chose to customize mine with hidden creature comforts (I added A/C, power windows, power locks, car alarm/keyless entry, back-up camera, big stereo, upgraded lighting, upgraded stock-appearing seating & interior, AOD transmission, engine performance goodies, etc.) and period-correct cosmetic mods (Cragar S/S rims, staggered sized wheels & tires, Lakewood traction bars, louvers, etc.). Anything I've done to my car can easily be undone if I decide to revert back to stock, with the exception of the aftermarket HVAC, AOD, and engine performance goodies.
It's your car - build it how you like! ::thumb::
