Bulkhead/Bonnet drain channel

I've got a rather cheesy 110 Td5 and the water drain channel/ rubber seal that sits between the bulkhead and bonnet has rotted to oblivion.

Can anyone tell me if there is a replacement or part numbers please. or is it fabrication time?

Thanks.

hi all,
I bought my 1987, 90 a few weeks ago, it had been very well looked after, and had had a good re-spray job done a few months ago, obviously there were, and still are a few jobs to do, ( that why we get landrovers in-it ), I have found that there should be a rubber gasket sitting between the bulkhead gutter flange, and the bonnet rear flange. original one was probably removed for the re-spraying.

question,, I have found rubber moulded sections, one with a side moulded barbed fixing section, and one with a top moulded barbed fixing section,, what one to get, and do I fix to bonnet or bulkhead.
