1964 and 1965 classic Minis had an improved sun visor that could pivot around to shade from the side as well as the front. This white plastic clip was used to support the outer end of that visor. Sold each, four (4) required. Ref: TRM129, GFK7344.
This part also interchanges with GHF1120 plastic bonnet rod clip.
See SV732 for sun visor.
