IRS issues

[grooml]

I am currently working on a MKIV with T-Bird type IRS. After assembling the knuckles with new bearings, hubs, and installing the rear diff, I continued on to install the control arm assemblies, and knuckles. However there appears to be an issue with the width. To the face of each hub, I get a total width of about 54". I thought it should be around 59". So, The halfshafts now of course are to long, and/or its far to narrow. I purchased these control arms from Whitby, and the packing slips show they are supposed to be for a "standard width IRS". Is it possible they sent me the control arms for a pin drive type of IRS. Any help would be appreciated. I am in Canada, a few hours north of Duluth, MN. I'm hoping I did something wrong, but I can't see where I can go wrong, its seems fairly simple.

It sounds like you have pin drive width control arms.

Are the spindle mounting tabs pointed up or out?

These are standard width IRS control arms.

As Mike said, the mounting tabs are at a 90* angle on the pin drive width arms.

Looking at the pic, I see Whitby did ship the wrong ones. The original order, and packing slips all show standard width control arms, but mine are pointing up at a 90 degree angle. Hmmm. More delays. They also shipped one 750lb, and one 350lb rear spring. I can't seem to get them to send the correct one. I've called them several times over the last several months. I hope this doesn't take as long. It kind of stalls the build. Being here in Canada also makes shipping slightly more time consuming.

Thanks to everyone for your help on this matter. It sure saved a lot of guess work, and phone calls.
