HiJet / Porter Van tailgate catch mechanism

I really don't know the technical name for the part I want. A pictorial parts list would help but sadly I haven't got one.

The part I'm after is the catch mechanism at the bottom of the tailgate that keeps the tailgate closed.

Because my tailgate was slightly out of alignment for about a year mine has worn to the point of non-functioning....almost.

If anyone has one or knows where I can get one sharpish I'd be grateful for any advice or offers. I'm willing to pay of course, just let me know what it's worth to supply and post it if you have one.

Cheers!

I may have one which would be outside in the trailer so will have to wait till the weekend when I have daylight cost would be post plus a bit for packing and the missus going to the post office I know there is some lock/catch assemblies but without checking I cant remember if they are for the doors or boot.

Thanks, Geezer.

I may have one on the way but I won't know till I get a reply, hopefully tomorrow.

ok no probs I know that I have the barrel minus key for the boot just let me know if you need me to look like I just need a bit of daylight to have a rummage.
