I'm sorry to say this but you appear to have a Bodged together Coil Connection, looking at the picture of the coil it appears the normal factory plug with retainers is cut cut away and replaced with the bare spades. so go to a junk yard and find a LT-1 and get the plugs or go to parts store https://www.autozone.com/electrical-...eVehicle=false
Not to throw a downer on things but current MSD coils are made in China. That being said, I had a USA made MSD coil on my LT1 for a short period before it failed. So if you have an ignition failure and suspect the optispark, the coil would be the easiest thing to check by a temporary install of a spare coil. I would be carrying a spare in my lock box to keep you from getting stranded.
it's funny you mention putting spare Coil in the Lock Box I did the same thing, the whole bracket that the Coil/ICM are mounted on just added 6" wire and Alligator clip for a ground just incase it needed it because it's normally hard bolted to Block even though it ran good when tested on a few min. run without wire.
I also carry a spare ECM and ICM. You can do a temporary emergency install of the ICM but you have to clamp it onto a heat sink of some sort.
Those towing charges can be expensive.

AAA platinum does me a world of justice! But ill keep the spare idea in mind for its future stamina runs once I get everything changed out.
in the 16 gauge plate i drilled (4) 11/32" holes to mount the icm/coil bracket to the plate and the plate to the crossbar. then i drilled and tapped the crossbar to 5/16-18 to mount the plate. i also had to splice the wires to accommodate the extra length of the wires. 1 wire crossed from the icm plug to the other plug so this wire i did not have to splice. wires were soldered and used heat shrink to cover then used a dei heat resistance cover to wrap the bundle. also as a precaution i grounded the icm to the plate and the plate to a bolt on the water pump.

I don't have a lot of experience with that, but it seems like a great idea and ill definitely consider having it done in the future.
i used a hypertech coil and a borg warner icm. when the weather gets 'warmer' i am going to trim the excess material off the bracket so you don't see so much of it.
