Can't find a definitive answer for motorcraft o2 part number(s) for 95

[murder_mobile]

This is for a 95. I've read dy649 & dy661 are the ones to get but I've also read 2 dy721's are what I need. Yes, I know its a pain in the butt to change them, yes, I know I need to go with motorcraft, I've researched. Just need to know part numbers. Thank you in advance.

the only difference, as far as i know, is wire length. longer wires will be easier to plug in.

2 dy661s should be fine. or whatever you can pick up affordable priced.
