Ignition Identification Help

[Spyder1234]

I need to set the ignition timing on my twin 350 Mags. I know it has a Thunderbolt ignition module, however the decals are no longer there. I am not sure which Thunderbolt version they are, but I do know they are original. The engines are 1987 350 Mags that are in a 1987 Wellcraft Nova Spyder. Any ideas on which ignition module came with that engine? I am not sure which version has to be put in "base timing mode" before setting the timing.

TB IV does not use a knock sensor or have a module attached to the dist body,, TB V does have the module attached and has the knock sensor
