Disaster What size are the ones that hold a TJ07 together?

I received free of charge a black TJ07 with rusted screws everywhere. What sizes were used, if anyone knows, for assembling the structure of the case?

Also, who has the most reasonable costs on replacement backplanes, etc? This thing got here pretty banged/scuffed up. It's honestly sad, but it's also a free $400 case. One I have definite plans for.

 

If they're like any other case, chances are they'll be M3, a very slight chance they might be M4 - but I'd say 90% likely to be M3.

 

M3 doesn't engage. Will try M4, thanks. Was wondering if M3.5, but the 3 should seem closer then.

 

Found some TJ07 replacement panels here. (UK shop though)

 

I think they are imperial...... 6-32 rings a bell somewhere?

I had problems screwing things into my TJ-07 and I remember 6-32 screws being the solution
