Thanks guys. I was relocating some of my vacuum stuff, and wanted to make some room in my engine bay behind my right front wheel well. The prior owner kind of just plonked the coil and the 6AL in the middle of a gap, and nothing else fitted. I had a brain-wave of piggy backing my coil on my 6AL. I've just finished mounting the 6AL horizontally on the rear side of the wheel arch about 2" below the top guard, and my coil vertically underneath that beside my washer bottle. My wheel well looks a bit like Swiss cheese now, but I'll clean all of that up when I get around to scrubbing back and dressing up my front end...
Thanks for the input guys. By the sounds of it, I made the right decision in not doing the piggy back idea 😊
