Where to buy spares for old motor home

[MotorsportTom]

First foray into this sub-forum so please be gentle.

My parents have a Fiat Ducato motor home (1995 registered) with a Auto-trail Cheyenne body on it.

One of the roof vents right at the front has a damaged plastic cover meaning in will obviously be letting moisture in although for the time being a tarpaulin is doing the job of preventing it.

I have googled and I can't seem to find somewhere that lists spare parts for this type of problem, that may be down to my ineptitude or is it a case you just have to suck it up and buy a whole replacement vent?

Over to you

Thanks both!

Dterry that looks just the job and have found a few potential matches on that site, just need to measure up to be sure now before ordering.

Appreciate the fast responses from you both
