[Hi Tech]

I've been researching the Fiero midengine V8 conversions, and I have a few questions, as I'm considering doing one, myself.

Some guys use a Longitudinal FWD transmission, such as a TH325-4L, from an '83-'85 Riviera, Toronado, El Dorado, or Seville.

What I haven't figured out, is how they use a "steering" axle on the rear, and how it becomes a "fixed" axle when they mount it in the rear of the vehicle.

Has anyone here done this type of conversion, or could someone at least explain how they make it so the rear wheels stay as a "fixed" straight axle?

The reason I ask, is that I'd like to experiment with a Buick 455, this transaxle that we're discussing, and build a midengine '70 Skylark or Chevelle.
If you really want to know why, it's just because I have all the parts to do it, and it will be something unique and different, and I think it would perform much differently, and better, with the engine behind the driver.

Thanks in advance, guys!
