Supply for table mounting bracket - Lunar H622

The table has two positions with two wall brackets on the van ( table and bed ) and a long hook/bracket on the actual table. The table hook allows for lateral movement with claw like protrusions to stop it from sliding fore and aft & tilting when leaned on. These claws have broken off.

I thought I'd found a replacement but looks like the company has ceased trading - see link below, any idea where I can get these from - searching the main suppliers hasn't identified a source
