Go to bed !
If I was you I'd still remove all of the spot welds and take off the whole member in one go. Surely it needs to be welded on for test though doesn't it? As long as there is more than rivets like my car hadCheers for the info. I'll most probably cut the old one away for ease as it's no good anyway.
Also I'll most likely bolt it back on if I can for ease of removal next time as the pattern parts aren't as thick material as oem ones.
