I just got done cursing the clutch swap on my 74 duster (I like the quick throw of the A-230 floor shifter, but I hate the bellhousing and three speed shift mechanism...I'll stick to 4 speeds from here on out...)...
Anyhow I have some pics for you, since I remembered you needed them so...
On the passenger side cross support you should have this adjustable "Idler" hook, leave loose until everything is in place :
On the driver's side hook the 'triangle' to the e-brake cable then hook your main loop through the 'triangle'
Before totally getting involved with those parts, you may want to look at your routing, the picture is darker (getting evening now...), Depending on the year and exhaust configuration: The cable generally goes over the top of the exhaust pipe,and under the tranny tailshaft...on some A-bodies there will be an "s" loop (kinda like an unfolded paperclip) that hold the e-brake cable away from the slip yoke and attaches to the crossmember or a spot on the tranny (this is to keep it from getting caught up in your U-joint or scoring up the yoke should the cable fail and "droop"/get pulled to the back...). My three dusters lost theirs or never had them, so I just route the line over the exhaust (on cat convertor models, under on supported pre-cat models), and under the tranny tail....
Last thing to hook up is the driver and passenger side wheel cabling, this is the "easiest" part...same on both sides:
Now once it all looks okeee-dokee and kinda hangin' loose there go back to here:
Squirt some oil on it, or some anti-seize and go to town with a deep socket.... (I like to use my 18volt cordless drill with a chuck and a deep socket). Drive it to about 3/4 the depth of your deep socket. Apply the e-brake, if a lot of lever/pedal comes out easily release, go back and adjust down another 1" of threads....
Note: some people will apply e-brake to desired depth and then wind the nutdown to adjust the brake this works, but I have stripped the threads on the idler hook doing it...
good luck mike! sounds like your project is coming long, I can tell you cussing at it regularly does help...
