So, my trade turned out to be a bit of a bummer. All 3 diffs were bad. I bought 2 complete new ones to replace the front and rear. I rebuilt the center with leftover parts. During complete teardown to install a full avid racing bearing kit, I found that the front hinge pins we're bent and the chassis looks like the ocean. Is it common to bend the chassis? Will good chassis braces help? I plan to scour flea bay again to come up with a new chassis. Are there any aftermarket options? Thanks for the help guys and gals.
