Laundry basket in howdens units

[cwr]

Hi folks

Just on the off chance.... anyone ever installed a Wesco pull out laundry bin into a howdens base unit?

The depth is specified as 503mm, but the Howdens units measure 490mm deep. 

Just wondering if its a case of taking the back off the unit,  or if just a little cut out is required for the runners. 

Thanks,
