G:

The only part number I can find is an S1V on the end where the pin is for the pedal. Mine (the z bar) is a two piece affair.

The lower (inner) portion of my equalizer has rougher welds than the outer/upper portion- making me wonder if it has been modified. Dunno.

All of this worked on the other car, but it had the cheaper headers that had no interference.

On section 5, page 10 of the Mustang/Falcon/Fairlane factory manual, mine is a two piece that looks just like the one in the photo for a 390/427 comet/fairlane. The other applications look different. In the drawing, it says "outer equalizer bar - 7528" with no id of inner equalizer bar. btw, that is the same number they show for the apparently one piece Mustang/Cougar z bars.

Thanks, Craig
