Joe,
Thanks for checking. LittleBeast indicated that mine is definitely not OEM. The crossmember has 1 1/2" drop brackets installed in those pix so those weld lines are not part of the aftermarket crossmember. Wish I'd taken some pix before install. I should find out this week if the drop brackets will work with the OEM crossmember.
Bummer about the CV boot. Are you next on the diff drop list?
Tom
