RollGuy's bracket looks well-made (haven't installed mine), but so does the other one in mountainmike47's photos, though the photos don't show how it looks installed on the engine. Broken Sanden ears is a common problem among hot rodders who use those compressors. Best to use a proven kit when you can. Nothing beats testing (my day job is a test engineer). RollGuy above found a slight problem in testing, with an easy fix, but left unfixed would likely result in similar rattling and broken parts. Loosening bolts and metal fatigue from vibration are hard to predict without testing.
