[my kids toy]

That center support bracket I see were it mounts in the hole on the left/center of the latch but I do not see the support there that the latch would bolt too and if it was there it would be very well seen in that first picture because you slid the latch over to show the 3 holes on the left were it mounts and if it was there you would have the bracket hole with the welded nut sitting there exposed as well.
That bracket will push the grill out as well and it has the welded nut on the bottom side of the bracket were your front and center bolt would screw into, right now you have a empty hole in the grill so it shows it is not there.
That bracket also gets mounted before your chevy emblem goes on because one of the mounting holes for the bracket is hiden behind the emblem.
That bracket will not push your grill out about a inch like it shows it needs so other tweeks need to be made as well. but the bracket needs to get in there.
