I have a 1996 Chevy Astro w/ 4.3 L vortec... these plugs fit that motor.
25mm
For plugs that can be adjusted the NGK catalogue states 0.8mm for all engine sizes of 405.
They are all different sizes.
I'm not sure for all available engine sizes, but for sure If it has the most common 104 motor, then the panel on top of the engine is removed with an Allen wrench, to gain access to the plugs and wires. The wires are usually very firm, but pull straight off. then just remove all plugs with the appropriate size socket.
There are comments that you should not adjust the gap sizes of the plugs and use them the way they come out of the box. Hmmm .. I have a 1999 Grand Prix GTP with the 3.8L V6 supercharged engine. My GM owners manual states a gap of .060 for all the replacement plugs listed not only for my engine but for all Grand Prix engine sizes of that year 3.1 / 3.8 / 3.8SC Check your GM owners manual .. it will state there in the section of different replacement parts, what spark plugs to use and the gap size

Plugs are different from regular body piercing jewelry because they are intended to "plug" a space. Plugs are used when people gauge (stretch) their piercings. Plugs are most common on lobe piercings, but can be used on virtually any piercing, as long as there is room to gauge. Plugs can be hollow or solid and come in a variety of sizes.
