Hi
Is this the XUD9 engine (1905 cc) ?
If so, this was fitted to quite a variety of Peugeot and Citroen cars and vans. Not sure if all variants used the same con rods, but it's quite possible. Used rods from a breaker would be a possibility, plus a new set of shells.
Bit unusual to need rods unless your vehicle has been driven through a flood !
