Where do I buy this?

It's the U joint adapter that attaches to the T Bird IRS pumpkin. Having a helluva time trying to find one

Mine came with the new driveshaft, I had specified the early IRS, possibly the last one built. I had to get a different front yolk to mate to a T10 spline, but that end bolted right to the rear diff on mine. A driveline specialist might have them.

I had my driveshaft custom built at this place. They have, or can get, anything I think. http://www.driveshaftpro.com/gardena# They are close to me so very convenient for walk in, but they may ship, I don't know.

You using the OEM T-Bird pinion flange? If so, I may have a u-joint adapter laying around you can have. I replaced my pinion flange with a Ford Racing part and had to update the u-joint adapter to match the new (larger) bolt hole pattern. So the old adapter is already off and gathering dust somewhere...

Thanks for all the suggestions. I bought one today from Denny's Driveshaft
