The HEI is the small unit. I made a bracket to hold the coil yesterday that will bolt in the original coli location.

I designed and made the power steering and alternator bracket system. I still need to modify the top bracket design so its not so long and it will curve to follow the alternator pivot center. I saw a kit a guy made before to hold a pump and alt but it required a modified head bolt and still with the braced back it looks like it wobbles when running. I was actually thinking of cutting up a bunch of kits if others want it. It all bolts to existing hole locations and lets you independently adjust the tension for the alt or pump without loosening the full system.
