I haven't tried any rockers myself, but Dwayne with Nsane Hot Rodz has been selling parts and stands by the stuff he sells. He sold me my cowl hood with a guarantee that I'd like how it fits or I could send it back for a full refund. You might look him up and give him a call to see what he thinks about the rockers he uses. I believe he uses either AMD or Key Parts.
