My "new" '74 Duster- or why I need a project like a hole in the head
Another update!
8 3/4 is in FINALLY. 742 case with 2.93 rear gears and an original clutch-style Sure grip. I also installed the hanger/shackle offset kit and AFCO leaf springs. The Afco's are 121 lb/in springs with a 5" arch (#20231M). I think typically these are circle track springs, but they're set up with a reinforced front arch so they fit the bill. Only minor snag was the 1" rear eye, but I found a set of poly's for a Jeep that fit the bill.
I was hoping that the 121 lb Afco's would end up close to zero arch, as they're only a bit stiffer than the stock rear springs. Looks like I hit it right, as they sit pretty close to zero arch, just a little above. I'm a little concerned how much they'll sag, but since I'm slow in posting this they've been fine for the last couple weeks. My XHD's on my Challenger had already sagged significantly at that point. If they do I can always bump to the next step up at 142 lbs, but since I'm planning on an adjustable rear sway bar I don't want to go too stiff on the rear spring. 225/60/15's are still on, look at all that room for bigger tires! 8)
Here's the ride height as it sits right now. I've still got some room to lower it in the front, but it's getting close to where I want it.
Next up is showing off my new March serpentine pulleys, and installing a Ford Contour electric fan set up so I can get rid of the power sucking flex fan I've got on there right now.
