The 4 coils on the bracket are AC delco with less than 4K miles on them. I can provide receipt for amazon purchase, if needed. The 4 other coils are OEM coils in working condition. Unknown mileage. Both sets of coils come on eBay relocation brackets. I may have a few more hanging around. Ignore the numbers on the spares.

The set of coils plugged in is self tapered to a piece of sheet metal that was bolted to the back of my KA head. Never had any issues.

The harness was made by me and is soldered at every joint. It’s fairly long as my car is wire tucked. Long enough to run from the back of the head, along the trans, through the trans tunnel and into the cabin where my stand-alone is. There is still pins on the wires, so it is a “flying lead”. the oem GM pigtails were resoldered together with a 14G positive wire (pink) and a 14G wire (black) for ground. The other grounds (yes these coils require 2 grounds) cylinders 1 & 2 were soldered together and 3 & 4 were soldered together (instead of 4 to 1) for better grounding properties.

The GM wiring is soldered to 14G wire, down to the ecu wire where it is soldered again. Everything has been wrapped in the nylon split loom and never had any burns / tears.

Price is $200 plus shipping.
