Technical Camper exhaust manifold!

[Luke900E]

Hi,

I own a 1985 fiat 900t camper and I need a new exhaust manifold for it as mine has a massive crack, the only thing I can find is one on ricambio which is going to be around £200 with shipping, I was just wondering if there was any more common fiat's that share the same manifold which I could get for a bit cheaper, I don't mind if its new or used. I dont need the whole exhaust system, just the manifold.

Thanks in advance,
