Thanks J,
Yes I've broken one of the bolt areas when removing. A previous owner had rounded off two of the bolt heads...the two lower bolts tucked in under the base housing. Neither would move even with narrow mole grips, two days of plusgas and gentle heat. Ended up using a recip saw and cold chisels. The cold chisel impacts to area are what caused the break. It could be welded but it would be much easier to find one spare that someone would like to sell.
Plus, thank you for the "need 50" points[?] note before being able to post in the wanted ads...hopefully someone will read this thread and pm me.
Rgds,
Andrew
PS it's an 11J 200tdi, though imagine they're the same housing for all 200tdi's
