In my 89 the MSD 6A I had was mounted up front under the Driver side headlight area (near the charcoal canister. or at least that general area.

I had a coil like that and made a bracket to mount to the rear of the Passenger side head (there should be enough room there for you too)

the FAST ECM I would suggest near the battery or the other side by the heater box, which ever looks for 'fit' and wire better for you..
