VOX ac10c1 WGS speaker choices that fit?

Has anyone verified that either the WGS retro 10, ET10,  or any other ceramic magnet 10" speaker fits in the Vox ac10c1?

There was a post here that mentioned that most, if not all, the 10" WGS speakers were 4-1/4" deep. The Vox AC10 will only fit a maximum speaker depth of about 4-1/8" without modifying the cabinet or chassis. For now, we are out of luck for a WGS replacement speaker for this great amp.
