Hi-cube rear door top slam panel / lock catch.

[hovis]

Hi all.

Not sure if it's a common problem but my P reg Hi-cube rear door top slam panel is slowly rusting at both ends inside the van to a point where when you lock the doors there is a chance the top panel + doors will simply pull out. It's bolted both ends so looks replaceable but the question is is that panel still available to buy new or as a pattern part..??
