chevy style HEI on 318
Here is a pic of my 4-pin HEI setup if it helps you. This is on the passenger fender as you can probably tell. Previously it had Mopar electronic ignition mounted on that fender. I used those existing 2 holes to mount a piece of L bracket. From that L bracket I attached the HEI coil/module bracket. This bracket is shown in that slantsix.org post I linked earlier in this thread. They can be found in lots of cars all over junkyards.
I had to modify mine a little. First the coil had a weird connector. I had to drill-out the studs or rivets (can't remember which) to remove it. I put a normal e-core coil in its place by using 2 long bolts in place of where the studs (or rivets) were.
The module was an 8-pin or something like that. I removed it and put the 4-pin there, it was a direct fit luckily.
Make sure you use thermal grease below the module and make sure it's grounded well (just ground 1 of the 2 module mounting bolts). In fact I need to add an extra ground wire to my module, I cleaned up the wiring recently and I forgot to add a new one!
