Ah, OK, i thought you'd have problems to get the aluminium brace in. See picture attached.
Where the bolts marked green and yellow in general don't make any problems, but the bots marked red can make problems to fit to the aluminium brace.
I'm not shure if all bolts are in one line. If they are and it is only a problem to get the 2 bolts on the red arrows side in line with the aluminium brace, this could easliy corrected with a ratched strap.
If the bolts are not in line on one side, this cross member has to be replaced.
