I could not locate a direct replacement for the original Hella relay, so I opted for the Echlin AR 274 replacement from NAPA. It was $18, more than double what the Superformance dealers list for the Hella relay. Installed it Saturday, works with no problems. Thanks to all for the info.
Rick - the baby came three weeks ago. I talked the wife into letting me take the Cobra out to "test" the new relay Saturday night. It was the first time I had it out since the baby came. There is no better therapy to counter a screaming baby and dirty diapers than a spin in the Cobra
It took me two hours to make sure the relay was working properly
