There were several wheel options and appearance accesories. And you could choose from a 3 speed automatic, 3 speed manual, or 4 speed manual transmission. Base price started at approx $2,300. The Fastback version debuted in october 1964.
Between 64 and 66 1 million mustangs were sold.
late 1964 - Inline six was upgraded to a 120 bhp 200 c.i. The 260 c.i. V8 was replaced with a 289 w/ a 2 barrel carb and the 4 barrel version was given 225 b.h.p. Also a better version of the 289 was added. It offered an autolite carb, cam, solid lifters, 10.5:1 compression, better air cleaner, dual exhaust, beefier connecting rods, larger bolts, and a bigger harmonic balancer. This resulted in 271 b.h.p. Wheels were upgraded to 14 inches on the V8's. The larger V8 came with a better suspension package and a 4 speed manual transmission standard. You could also have the drum brakes replaced with upgraded disc brakes, quicker steering, limited slip diff. and under dash a/c were also options.

If you got all the options on a Mustang it roughly equaled the price of a corvette.
1965 was the first year that Rack and Pinion steering were offered.
Upon making of the millionth mustang Ford released it's first commerorative Mustang, the Sprint 2000. This was just a simple dress up package for the inline 6 motors. It came with pinstripes, a center console, and a chrome air cleaner that said Sprint 2000.
The majority of 65's and 66's sold were three speed notchbacks.
1967 - 68 Mustangs had a few changes. The entire car was slightly bigger, suspension, steering, and brakes were all upgraded. Ford also added the option of a 320 b.h.p 390 c.i. big block V8.
The 390 was a cast iron block, cast iron crank, two bolt mains, hydraulic lifters and a 600 cfm Holley 4 barrell carb. The Gt option began to include, stiffer springs, adjustable gabriel shocks, 3.25:1 limited slip, front sway bar, 15 wheels with imitation wire hubcaps, and 16:1 steering.
There were approx 25K verts made and 42K fastbacks made in 1967.
Ford also added a tilt steering wheel ( $ 60 ), fold down rear seats ( $ 65 ), and cruise control for the V8 auto tranny's ( $ 71 ).
In 1968 Semon E. Bunkie and Larry Shinoda came from GM to Ford and helped design the Boss Mustangs. The Boss was originally to be called the SR-2. Shindoa was responsible for the front and rear spoilers on the mustangs, as well as the addition of 7 inch wide wheels on the boss models.
Boss packages ( released in 1969 ) included : Boss 302, Boss 351, and Boss 429 which was produced simply so the car would qualify for stock car racing.
April 1968 - the 428 Cobra Jet was introduced. It offered 400 b.h.p, 14 second 1/4 mile times, and a ram air hood scoop. The rear end was also upgraded to 3.50:1.
429's were made form nodular cast iron, 4 gallery lube system, 4 bolt mains, forged crank, forged rods, alloy heads, oversized valves ( 57.9 mm intake 48.3mm exhaust ), 735 cfm Holley 4 barrel carb, dual point distributor, Hydrualic lifters, mild cam, and free flowing exhaust. Cylinders were each sealed with copper rings instead of head gaskets and O-rings sealed the oil and water passages. 429 were notorious for running bearings due to poor oiling systems. Only 889 Boss 429 Mustangs were built and very few of them have survivied today.
Mach 1 Package was basically cosmetic. It included a flat black hood, fake air scoop, optional hood pins, pin stripes, chrome gas cap, painted mirrors, and a cosmetic suspension package. Mach 1's came standard with a 351 V8 w/ a 2 barrel carb.
In 1971 the Mustang recieved a major face lift. It was an inch longer than previous mustangs, and two inches wider. The 200 c.i. engine was replaced with a 250 c.i. 145 b.h.p. I-6. The 210 b.h.p 302 was the standard V8, followed by a 240 hp 351, 330 hp 351, and the 375 hp 429.
In 1972 the 429 and the Boss 351 were dropped. wich left the 351 Cobra Jet, 351 Cleveland, and the 250 I-6.
1973 the front grilles were changed slightly, painted front bumpers were added, and the performance continued to drop. 73 mustangs were approx 800lbs heavier than previous stangs.
125,093 mustangs were built in 72, 135,867 in 73.
Ok that's enough for tonight, I'll post the info on the 79 - 03 Mustangs later. I'll skip the Mustang II being as it almost destroyed the mustang name ( sorry any Mustang II owners )
