The crossmember is held to the frame by 14 bolts. 12 of them will line up perfectly. The remaining two are about 1/2 holes width off. Just bolt in the first 12 to get it in and aligned properly and enlongate the last 2 holes with a grinder till the bolts will screw in.

I've even done the swap and just used the 12 bolts and not worried about the remaining two.
