Driveshaft yoke?

[supercrackerbox]

Quick question: I'm going to be swapping a 200-4R into my Regal, which originally had a Metric 200. Will I need a new driveshaft yoke for the trans, or will my old one fit?

They are all 27 spline up until you get into TH400 territory. That is 30 spline.

Cool, thanks.

The TH2004R's trans mount is is farther back than the TH200.

The measurements do vary from site to site & page to page. I don't know why but, every site I look at has slight differences. Including TCI's site.

Got the crossmember already, need to pick up a new mount though. And I have to get the driveshaft shortened for the 8.5" rear.
