I take back what I said about being able to repair the front cross member without removing it from the side rails. There's been a whole lot of fix'n going on with this cross member.

You can rest assured that the nice matching of the bolts is nothing but a coincidence as this is very likely not the original front cross member, nor the front motor mount bracket. With your legless center cross member, I would expect to see a front cross member and front motor mount bracket spacing on centers of 15 inches, not the 12 inch spacing in your photos. Given the extent of the modifications, including to the back of the cross member in the center, I can't say if it is an early so-called flat cross member (as opposed to the super-early, Model B only, 'flat' front cross member with 15" on center spacing.

Examples of the 15" and 12" spacing cross members and front motor mount brackets are shown in the photos below.
