On your application, you should have an external coil; on the external coil there is a module that is mounted to it. The coil is a canister style coil that has terminals on it; this is where the interface of the MSD Unit will be.
The coil has a positive, take all the wires of the positive side and connect the wires to the small red of the MSD unit.
Take all the wires of the negative side of the coil and connect to the white wire of the MSD Unit.
At this point there should no wires on the coil, then from the MSD Unit you will take the orange and connect to the coil positive and small black to coil negative, these will be the only wires on the coil.
The only wires left will be the heavy red and heavy black, which will go to battery.
Once connected if the vehicle does not want to start, but there is spark you will need the PN 8910EIS Tach/Fuel Adapter. This will have the instructions on how to connect to the MSD Unit.

Do I need to use rev limiter modules?

I also have the tach adapter, but no diagram.

What's the carb number?

Thanx again

No you do not have to plug in a module in order for it to work, the only thing is that you will not have a rev limit.
Here is the link to the instructions of the PN 8910EIS,

The CARB # is D-40-26
