So my story in short ish, thought I would replace the w brace, bolts snapped etc taking that off, the got if off and found the "liver" shaped parts it attaches too was so corroded (like nothing left) they had to be replaced which is attached to a sheild (just in front of the fuel tank) was corroded and need to replaced (not essential but need to do a proper job) . I looked at this all on a proper ramp and could see this needed somebody who had done this before as you had to get various things out the way. £600 pound later at the Nissan dealer (with looked after on price!) -without the w brace!! (But all new bolts/nuts) it was finished until I started it and found the flexi pipe was blowing because that was corroded which then was blowing so then it's a new y pipe and cutting off the bolts to get that off. Finally done. What a nightmare, never again 😪😪
