Service guide available from Ford in album (7)
I believe the answer is:
ordinal
'service guide' is the definition.
(guidebook for a religious service)
'available from ford in album' is the wordplay.
'available from' indicates a hidden word.
'ORDINAL' can be found hidden inside 'ford in album'.
(Other definitions for ordinal that I've seen before include "Ninth, maybe" , "Number such as first or second" , "Number in a sequence" , "Possibly first or second" , "Kind of number defining position in series" .)
