I'm quite new to this wonderful group and would like to add a supplier to your list. Obvoiusly I cant actually do this, so here are the details for you.
I needed a centre pipe for my 97 2.5TD LWB San Diego and found that prices were quite high until I checked out Viking International. They used to be Birkenshaw.
I managed to get a centre pipe for £66.04 + VAT and thought this was a good deal. They have warehouses all over Britain.
I'm a mechanic and got one through the trade, so you may be asked to open an account. It may be worth FOG looking into trying to get some sort of deal going with them, the manager at the Newbridge warehouse (Edinburgh) seemed to think it may work. Their website address is as follows.
