Default Fabbed Aluminum diff crossmember

I guess this will be my first post on the board since i found this place. So far this is my first winter project that I completed. I'm pretty happy with the results.

So it started out that I was just going to make those aluminum disks to shore up the diff crossmember bushings. But it turned into a complete fabbed aluminum crossmemeber. And since i had to cut those ugly spring bolts I fabbed up some adjustable hiem joint spring links. I took it for a test drive and the rear end feels a lot better. Now I just need to get some sway bars on the car.

Thanks guys.

The cross member ended up 12 lbs lighter than the stock piece, weighing in at 10lbs total. I used 1/4 wall aluminum rectangle tube. I would have gone with thinner tubing but my analysis software wasn't cooperating and didn't have time to figure out why.

I left the diff at the stock height. If the round end's were machined longer yes the cross member could lower the diff.
