Cant find case clips?

[Knappers]

I've got a boiler with case clips missing and as case forms part of 'gasway' the boiler was classed as AR.
Now I've come to it and am struggling to find the parts.
It's an early worcester greenstar R28 he
gc: 41 311 62

Parts arena shows screws and slots where you attach bottom of case to boiler but my boiler has square holes that (In my head) use sprung metal or square plastic clips?

If I zoom in on 'assembly overview' in parts arena then the schematic shows my style of mounting plate but on 'sheet metal' parts list it changes style....

Now if I can't find the clips then I'm left taking an expensive punt at changing mounting plates and front case and hoping they fit.

Can anyone pls help me find the part it's about 10mm square in plate and case that match up.

I'd happily take some from a scrap carcass!

You got a pic of the clips ?

From memory doesn’t this have spring levers

This is what it is.
The little square hole front bottom edge

This is what it changes to on parts list.

3 calls to worcester and over 30min on line didn't help

In manual I found this which is what I want but doesn't relate to any part number I can find.

Then later in same manual it shows this.

Stud coupling and grind two channels in so it can fit in the grove

I might just put some self tappers in and be done with it!

Would a standard snap in 'cage nut' do the job? 3/8" square (9.53 mm x 9.53 mm) is a standard size for the cutout.

Fairly standard plastic capitive nut would also do...
