Some circulated recordings of the Faces set include Peel links. At the end of the show, he thanks Argent for their earlier set and says he'd like to apply for a job as a roadie with the Faces. This would put the show on this date, according to Ken Garner's The Peel Sesssions (p. 212).
Sources such as the Ron Wood Database site have the same tracks in the Sunday concert show broadcast on 29 November 1970, but this appears to be incorrect. PS this seems to have been corrected for the 29th November and the details for 5th July have been removed.
A fine quality FM recording is available on the file below, but the details on the site again mistakenly assign the set to the 19th November and broadcast on the 29th.
