Stock suspension is a type of four link..IMO.. that said, you probably could put a straight axle in, but you would then have to fabricate a new mount for the transmission, as the driveline beam would have to go. I've thought several times about methods of adding a rear tranny mount that would use the current beam mount point and current suspension mount point with the idea of being able to swap back and forth between straight and independent rear. Now...I have no plans to do this myself, just thinking one day. Musta been too much pizza.

The stock suspension is a 10 link.
4 of them work just like a 4 link on a straight axle.
The other 6 ( 3 on each side ) control toe in and camber. On a straight axle both toe in and camber are fixed to 0.

More likely it was the stuff that was used to wash down the pizza (just kidding!). I think some guys have actually done this with a C4 - the straight-axle I mean. Anyone?

If you get one to run faster than a specified number in the 1/4 mile, the straight axle becomes required. If you run 10.99 or quicker the independent rear must be replaced with a fixed axle if over 2,000 lbs. (page 22, 2002 NHRA Rulebook)

Yep...it can. You would have to fabricate mount brackets to allow the upper and lower trailing arms to bolt to an axle, and you would have to make a panhard bar and support, as well as use coil over shocks.

As for the transmission...you would have to fabricate a trans mount and crossmember...maybe use an X brace from a convertable.
