Anyone had to replace their wheels on these old grey cases?

Have been trying to find some online from wheels suppliers rather than Scicon.

Specs are 50mm wheel

50x45mm plate with 32.5mm hole centres

Stack height 65mm

Was looking for something more sturdy than the original ones

No joy searching so far

Any help appreciated

I'm not sure of the wheel dimensions but I bought a set of replacement wheels for my scicon hard case over at wiggle. I believe pbk has it as well.

I'm based in the London (UK) and have been trying to sort out replacement latches for the non tsa aerotech hard case (black). I tried all the local shops and had no luck. I ended up contacting Scicon directly from their website using their Skype link and had great service.
