1973 Mustang General Information
The 1973 Mustang resembled the 1971 and 1972 Mustangs very closely. The front bumpers, front fenders and grille are slightly different. However, if you look casually at the cars, the average person will not be able to distinguish one year from another.
Bumpers and bumper mountings were modified to meet the new federal crash standards.
Engine availability changed in 1973 because they no longer offered the 351 HO engine. You could get the 351 4bbl adn 351 2bbl as an upgrade from the 302.
This was the last year for large and performance cars for about the next 20 years. The next performance car Ford will make will be in 1983 when they make a GT with a 4bbl carburetor. The Lee Iacocca Mustang II made its debut in 74 and thereafter for the next 4 years.

- 1972 Mustang Coupe 302Just purchased a 1972 302 V8 coupe as a project. Picked it up in CA from a vet who had it in his garage, barring the occasional grocery run. The car runs incredibly well, the interior is in great shape and I finally snagged it after years of wanting one. There is some body work […]

- New to the Group!Happy to join this group. I found and purshased a great '72 Coupe that already had a completely restored engine and drive train. The exterior body work was almost complete as well. So I've been focusing on restoring the interior with new OEM parts where available but I've wasted some time and money on a […]
- What is the best rear axle ratio for our cars?I was just replying to a thread from jscott about a noise he is hearing that sounds just like the noise I am starting to hear. It seems the general consensus in that thread is that it is probably the differential failing, which I expected from my car but was trying to get the rest […]
- 1973 Convertible Project: Undercoating Decision TimeWell, I guess I did it. I got a second 73 Project car. Now, while my 73 Coupe (Grande) looked like a basket case (BC) project when I got it, I might have just found one that is one basket short of a BC. Ok, the Pros and Cons: PROs Looks like it was a […]
- SubwooferLooking at putting a powered subwoofer in my 1973 coupe. Considering the type that sits under a seat, but not sure any will fit. If I put it in the trunk, how will the sound deadener I have installed affect the sound? Anybody else go this route?
- Strange noiseOn my way home yesterday, after driving the car for 2+ hours I started to hear a noise. It sounded like if you were driving past a saw mill, a high speed metal noise that would come and go. When I would take my foot off the gas it would stop immediately, Revving the engine […]

- Power Steering on1969 Shelby leaks from filler tubeWhy would a (like new) power steering pump on a 1969 351 push fluid out the filler tube. It's not over filled and I replaced the dipstick in case that was it. The car also steers hard when the car is barely moving, but steers fine when driving down the road. I don't mind replacing […]
- What did you do today instead of working on your Mustang?For me I am waiting on the 71/72 weld / sealant book to show up. No book = no seam sealer going on the car yet. So instead of working on the Mustang I decided to work on my daily driver project instead. Master cylinder was leaking on the diesel 83' GMC 4x4. In the process of […]
- Rear main seal on 1969 351 windsorAny suggestions on replacing the Rear main seal on 1969 351 windsor without pulling the crankshaft. The 1/2 of the seal between the block & crank shaft is what I'm looking for suggestions on. I'm replacing the oil pan gasket (one piece) with the motor in the car.
- Duraspark II with ram air debacleMy new to me 71 Mach 1 with 351c has a mish-mash of parts that I am trying to sort out.
