where does one find a 3/8 inch spark plug socket socket? I can only find 5/8 inch and larger.

Unless these are somehow the tiniest spark plugs in existence, you do not need a 3/8” socket. 5/8” will be the correct socket size and 3/8” will be the size of the ratchet attachment on the other end of the socket. 3/8” is about 10 mm which is smaller than the threads on this plug.

will this fit 2004 dodge ram 1500 4.7 liter 4x4 v8?

No, these Autolite XP3923 spark plugs fit 2002-2005 Dodge Ram 1500 (3.7L). Autolite XP5224 will fit 2002-2007 Dodge Ram 1500 (4.7L V8).

Will these spark plugs fit 2003 Altima 2.5

Hello, no these will not fit a Altima. Ngk are the original part number 6240. Please let us know if we can be of further assistance.
