Canon T90 lens mount is loose. Easy repair?

Hi everyone,

Well my T90 arrived today and cosmetically it's in pretty good shape save for the scratches shown on the listing. All the functions seem to work properly, there's just one problem. The lens mount is loose.

Is this something I can adjust myself? Or is it going to be a serious undertaking?

Any help is greatly appreciated!

Turns out it's super easy! Just a few screws to undo the front faceplate and then you can tighten down the lens mount. Good as new

Slightly different question but along the same lines.

My FD 100mm f/2.8 is also loose. There is a slight bit of play in the mount. Without completely disassembling the lens is there a way to fix it?
