I mounted my ignition box where your coil is.
No, it actually fits the large dizzy shaft hole block. If you have a read of the "the pillow block" thread, my car has had a block change somewhere along the way or had the shaft hole drilled out.
But its not a problem, someone like IC&E in Melb can convert it for you or just get a machine shop to mill it down.
Only restrictions with the 8580 are that the least amount of mechanical timing that is available with the parts they supply is 18 degrees. With the alloys and high comp (11.4:1 in my case) that means that I have to set initial at 12 degreees because it will only stand 30 degrees total. In a perfect world, I would like to run about 18 deg initial and have 12 deg in the dizzy.
I am going to change the springs that control the rate of advance that comes in. They come with the heavier springs installed (slow advance) but I will change it to the lighter springs for more advance earlier. I am hoping I will get away with this without introducing pinging too early as the alloys will stand more advance due the centrally located spark plug in the combustion chamber
(For those who don't know, MSD supply the dizzy with 4 different mech advance stoppers and 3 different spring weights for rate of advance)
I thought about putting the 6AL where the coil is but as the coil is not suited to mounting on the engine I decided to go the way I did. Only other option was to go inside with the 6AL (too much work) or mount the 6AL on the front of the shock tower where you did and put the coil down under the washer bottle which would look a bit dicky and is not practical to have a long lead running down near the power steer pump
