You won’t find anything specific to the F-Body because no one has done it (that I know of). The Dakota cross member I’m using comes from Industrial Chassis in Phoenix. It’s for swapping the Dakota IFS into an older Ford truck. The specific unit that I have is actually no longer being produced by IC. I got lucky and found it through a HAMB guy. IC IS making new and improved units now however (also for Ford trucks). Check them out…

I think the price is $795.
