hi and thanks for all your info
the one i am taking out is a motorcraft bxt-65-850 and was garanteed for 84 month but i don't know how long it has been there
i take it the 65 is the a/h and the 850 is the cold cranking rate i would like one the same if pos phoned the mega store but no answer have to Waite till after the holls all other links don't give the cold cranking is this relevant or am i to fussy?
