fyi, I can't STAND that damn upr triple hook quadrant. Positioning of the hooks is all fubar'd. Causes the clutch to grab MUCH too high no matter how you adjust it, and a big mushy pedal up top. It works, it just sucks.
You "may" not have luck with that ford quadrant, an oem cable, and a firewall adjuster. That quadrant, while very nice, is a very old design, and specifically designed "before" the days of firewall adjusters. It was meant to only work with an adjustable cable.
See my picture below, the blue quadrant is the one you just bought. pay no attn to the color, they came in different colors. you can see how much longer it is over the competitors. This extra length becomes a big problem when using the shorter oem cable in conjuction with a firewall adjuster. I had luck running a ford racing quadrant with an early steeda fwa, however, that was on an oem cable with 150k on it, and likely stretched out. You may damn well find that with a fwa, the oem cable won't work.
In that case, a longer oem sn95 cable may just be your answer, but that's untested on my behalf.
