Hi Ed, are they the same blank for each end? I've seen these on ebay
http://www.ebay.co.uk/itm/EGR-valve...arts_Vehicles_CarParts_SM&hash=item1c28366216 and wondered if I need two of them, or just one for one end, plus a different one for the other.
I cannot shift the two bolts that join at the valve itself and know they're going to sheer, just like yours did.
edit - if I need another plate for the opposite end, please can you supply link/contact details for your seller?
2nd edit. - \i have just seen from your photos that the two ends are shaped differently. I still am unable to find the plate for the other end of the pipe though on fleabay
