B22 clutch and stands

[yosemite]

Hi starting to rebuild and work out what is missing from my 1937 B22, and looking for parts
The first is the clutch centre and  inner race, was wondering  would it be possible to fuse a later type thinkinbg I may have one in a box somewhere.
Next both front and rear stands are missing can anyone suggest an alternative I could use.
Thanks
