hi there, i worked at a breakers yard and to answer your question, no they are not the same infact they are quite a nightmare having mailed out several times the wrong type, the differences i come across are, four branch type, bolt hole positions, and size, i recommend taking yours with you to get another or if mail ordering send an e-mail picture of it, heres where you might get one at the right price e-mail steve@autobreakers.co.uk, www.autobreakers.co.uk, hope this helps you.
