SWB jump seat

Hi does anyone have a spare bracket for a Series 3 88" back seat - ie the bit on which the seat base pivots (see photo) or point me to a supplier? Actually, I just need half of the bracket as I have the bit which bolts to the seat but the bit that bolts to the tub is lost. So if you have a broken one I'll take happily settle for that. (BTW - my apologies if this seems to be posted in the wrong part of the Forum - I tried to post in the 'wanted' section but was rebuffed with a message saying I didn't have enough privileges to do so - perhaps newbies have to earn that right?)
regards, Justin

I have an assortment of brackets, but cant get to them till Monday, am sure I will have 1 if your willing to pay the postage you can have it
