OE GM coil - it replaced the old original coil in my 2003 Chevy Astro Van with a 4.3L V6 engine. The van one morning just would not start, I tested fuel which was fine, I checked engine timing which was good, I checking for spark which meant I had to remove the engine doghouse. I tested for spark at the coil wire - no spark. I looked closely at the coil and when I turned the engine over I could see it sparking to the coil bracket so I ordered the coil and since the distributor cap and rotor we original equipment I decided to order those items and replace them as well. By the way, the coil on an Astro Van is not easy to replace. With those parts replaced the van started with no problem and has ran great for the past four weeks, problem solved.
The original coil is riveted to the coil bracket, the rivets must be drilled out. This coil DOES come with all the bolts, nuts and other hardware needed to attach it to the coil bracket.
