I have used just about all the bubbles on the market but the best i have seen would be ben snobars version .the problem wont be in blocking most are ok in the casting ,but the grills wont fit and all the bubbles need the grill holes reshaped and the center bar is way to wide .that said since your going custom just buy cheap the ebay bubbles tend to show up every few months ,again since your going custom if your installing the grills thats the issue.
