I believe seat pans for coupes and convertibles are taller than the ones used on Sports roofs/ Mach 1s. That may explain why they are taller if you are fitting them to a Mach 1 or Sports Roof.

There is a product called "belt dressing" that I used years ago. It is an aerosol spray you apply to the tapered belt surfaces that gives the belt better grip on the pullies and reduces/eliminates squeaks. Got it at a local car parts store. Idler pully and or/ AC clutch bearings can also...

Here is the diagram out of the 73 shop manual. As mentioned already the valve in the engine compartment should be normally open. Vacuum should close it when the temp lever is moved all the way to cool. The temp control cable connects to a pivoting arm, the arm pushing the water valve vacuum...

There is typically a 1/2" square hole in the front of the adjustment bracket for tensioning purposes. I use a 1/2" short ratchet extension on my ratchet to hold the belt tensioned while tightening the bracket hold down bolt. Mine has a 351C engine.

The switch mounted on the transmission made contact only when the transmission was in gear (forward or reverse) and not in neutral. So the the light and buzzer only come on with the trans was in gear with the ignition on and the driver seat belt not extended (passenger seat also if occupied...

All 73s had it, and I think 72s had it starting about mid year according to the 72 wiring diagram.

You may also need a starter, they are different than the one for an automatic. The "Z" bar pivots will be needed also, one mounts to the engine/bell housing area and the other to the frame and the bearings that go on those. Also the rod the connects the clutch pedal to the Z bar and the rubber...

It was part of the appearance protection package option I believe. Also available from a Ford dealer parts dept. If part of the option package it's key was the same as the trunk key and if you had the optional convenience group the same key was used for the glove box door. The appearance...

I have one of these if interested $100 plus shipping.

The standard 73 Q code was equipped with a 4300D carb that included an electric solenoid that held the throttle open a bit while the ignition was on. Idle speed would be set with the solenoid energized. When the ignition is off the solenoid retracts and lets the throttle close more fully...

Just checked, the version I have is for the 70 AMP alt. 70 amp alts are only used on 73s with rear defrost.

I might have one. 70 Amp alternator? Or a less amp one? The connection at the alt is different between the 2.

Mine is 3 piece also, I have excellent side pieces available, but not the center piece. The windshields are different between Mach 1s and coupes/convertibles. As far as I know the bright trim is not interchangeable between them.

The 3/4 vinyl roof was an option for 71 an 72 also, although quite rare. 73s had that option prominently displayed in the Mustang sales literature, 71 and 72 did not. I think that is why a lot more 73s have it. 71, 72 and 73 early production used a bright metal black and shinny trim (like...

The two wire connectors go to a EGR cut out solenoid mounted on the driver side valve cover inboard front corner. The 73 wiring diagram shows the connections and the solenoid. 4 speeds for 73 also used another emissions related 3 port valve mount on the passenger side rear corner area on the...
