Just a note to say my first post has been edited to say the charging lead & the Ram connecting arm were not included; I already had these. For me, the clever bit is the Ram ball attachment; I don't think anybody else supplies this. Bob was keen to show me that he also has an attachment for the stem nut, but the nut needs to be removed & machined (which he will do). I have used the UA holder for the last few years & would say the one from Bob seems to be of a least equal quality.
