Wow. I didn't realize that vintage riviera was FWD. Buick was sort of a grandma line back then so I didn't pay them any attention.

One difficulty you may run into, the pick up point for your toe link is critial in 2 dimensions. If you're off, you'll have rear bump steer, and that can be very unsettling.

I don't know if those uprights were front or rear steer, but I would use the with the toe link to the rear, so any control arm bushing compliance gives you understeer rather than oversteer.

You can see what I did here.  http://www.lonestarclassics.com/lscbb3/viewtopic.php?f=3&t=1861&hilit=IRS

If you're not using the halfshaft as a suspension memeber, the late (2000- 2007 or so) Explorer 8.8 is a good unit. LSD's are cheap and plentiful, and the aluminum case saves a few pounds.

I think both arms need to be angled, espacially if your upright joints can't twist.

I didn't put any antisquat in my Cobra IRS. I was more after cornering stability than quarter mile times. With the low CG and stiffis suspension, the squat isn't bad like it was in my old 280Z.

I don't think FFR has any either.

What are you using for an upright?

I think the Viper upright uses the Dakota 4x4 front wheel cartrige bearing. And there are a ton of wrecked Vipers. There are a few ebay sellers that specialize in dismantling them. A Dodge salesman told me 6 years ago that about 20% of them come back totalled within 3 months, and half of thhe time, the buyer get's another.

An option I don't see explored a lot here is using mid sized 4x4 truck front spindles for rear uprights. Somer of the newer ones are aluminum and light weight and use easily and economically changed cartrige hub bearings. Then all you need is a couple of frankin axles and control arms. One issue though, if you use a front spindle, the pick up point location is critical in 2 dimensions or you'll have a bumpsteer.

That worked, so here's the other angles.

Here's what I came up with. It's a piece of 6" shedule 40 pipe, 3/8" plate for the bearing mount, 3/16" and 1/8" for the pick up points.

That's one of the coolest and most inovative things I've seen in a while.
