So, I have decided to go with TFI coils and HEI modules for my direct fire ignition system.
I am in the process of finishing the brackets for the coils and I don't know where to mount the modules now.
Here's a pic of what I have so far. Any recommendations?

 

For the TFI coils, I recently modded the stock coil clamp and was able to place them
there. I don't use the trailing so I didn't need a 3rd coil for that. I don't have a pic of
it but it looks real clean and it's easy to miss the fact that they are not stock coils.

I like your coil mount, looks clean and easy to access.

For the HEIs you want a plate of AL about 1/16 or 1/8 thick to mount them
on to act as a cooler. Use thermal paste on the back of the HEIs to make sure they
make good thermal contact with the plate. Then take that plate and mount it
somewhere close to the coils and the dizzy. I used the old stock SA ignitor box
mounting plate to do all this and left it in place on the front of the shock tower.
