The block was a 3 Bearing Series 3 Diesel, prefix 906. It is my understanding that the block is the same on a petrol engine so the caps are probably common to both but you will need to check that yourself. Included in the sale is what you see in the photos.
The 3 Main Bearing Caps with Bearing Shells still fitted. The 6 Bolts and Washers for the Caps.I still have the block, the front cover and the oil pump if you are interested.
