Which crankshaft pulley?

Hi all,

I am looking to fit power steering to my 2.5 petrol. I have been looking for a twin crankshaft pulley. From looking at the official one for the 2.5 petrol i believe it is a ERC5128. However, new they are mega money and I cannot find one 2nd hand. Therefore I was wondering if a ERC5348 (from a 2.25 petrol) would fit? They are much much cheaper! Not sure if they share the same crankshaft?

Many Thanks in advance

They don't fit.. you cannot find them second hand. New they are expensive and most of the time unavailable. I needed one for a project some time ago and tried to order a new one without succes. So I had one made for me on a lathe for even more money. I few days later the original one arrived and lrseries refused to take it back. So I do have a new spare original one that I could sell, but not for much less than the list price..
