a Frenchman who needs advice for GM HEI MODULE!!!!
RRR, If using the GM e-core coil like me, the ones I got at the junkyard have a bracket which varies a bit depending on engine. GM mounted it on the intake manifold. Below is how I mounted on the right inner fender of my 1964 Valiant slant-six. Can't quite make out the coil's bracket, but I recall a simple L shape. There are 2 holes thru the bottom of the coil laminations so you could easily roll-your-own L-bracket. The closest you can mount to the distributor, the easier, and near the HEI module if using the GM cable between them like me. Note that I still have wire nuts from verifying polarity of the 2 pickup wires from the Mopar e-distributor (my custom wires don't tell you polarity). The heat sink under the HEI module is probably overkill since GM just mounted to an aluminum plate inside the distributor. I cut it from an old PC CPU heat fins.
Note that I also mounted the Vreg near the distributor which seems simpler than way over on the firewall as Mopar did and I already had IGN power there for the HEI. For those wondering, I added a vacuum-operated valve (vacuum shuts, spring return) to block heater flow when the AC is on. A little electric valve beside it passes intake vacuum from an "ON" signal wired from inside the knee-knocker climate box. Not really needed since the regular cabin blower is off when using AC, but helps manage the heater hoses. I use silicone hose (blue) whenever I can. Also plumbed in a heater core protector valve.
My 1965 Newport 383 when I was testing polarity with a timing light, as I explained (spun shaft by hand). Twist the pickup wires to avoid positive feedback by picking up the sparking. The yellow wire is grounded so the sparks jump to it. Note the reluctor teeth align with the pickup when the lamp flashes. I inadvertently had the HEI pickup connector on wrong (fixed), but the photo doesn't show the dbl-bullet connector polarity anyway. I mounted the HEI atop the York compressor since convenient. Also can't see the GM bracket, which was your question, but I recall I cut it so just 2 flat metal plates which are clamped on each side of the York bracket.
