1994 coupe Coil removal
Trying to remove the coil from my vette. Can't seem to locate the mounting bolts. Any one have locations of mounting bolts or a pic showing their location? Any response is much appreciated.

The coil shares a mounting plate/heat sink with the Ignition Control Module (or ICM). The ICM/Coil Assembly comes off together via 2 bolts that go into the front of the head. The left bolt is shared by the power steering reservoir. I believe they are 13mm. The right bolt is behind the wire bundle. If you remove the lower power steering reservoir bolt as well, it makes it easier to remove the assembly. The coil is riveted to the mounting plate. Grind off the rivots and replace with screws. When you reinstall, be sure to put new heatsink compound between the ICM and the mounting plate as well as between the mounting plate and the head .

Hello again. I've finally had time today and removed the driver side bolt no issues. When I removed the power steering side it was a nut. After removing the reservoir this allowed me to see what appears to be a two sided bolt that has to be removed but seems stubborn. Is the side going into the block left loose right tight threaded? Any in site on how to remove without breaking the bolt off?
