Falcon XA-XC mirror spacers for Capri Mk1

[allanv6gt]

Anyone know where I can get some of the spacers to adapt the Falcon XA-XC series mirror to a Mk1 Capri ?

My carefully stored and saved original bullet mirror is next to useless in practice (sorry, not for sale)
(ha ha...I'd forgotten that little fact from the '80s driving a diffrnt Capri)
....and maybe I'm now used to the convex see-everything-but-closer style of modern car mirrors
