I have not actually fitted it yet but will keep it as a backup and I fully expect it will work when I need it. It appears to be of good solid build and the correct size to bolt straight into the original mounts. Price and turnaround time was very good. The primary coil resistance measures on an Ohm meter correctly for the Holden 202 HEI, which is the main thing electrically. The secondary coil should measure 8000 ohms (Commodore VH Gregory Workshop Manual is my source) but it only measures 5500 ohms. I'm sure the coil will still create a spark but likely not as "fat" a spark as it might have, due to the reduced ratio of coil turns.
