Nunyo, Thanks for this information !!
(Auburn, I think you may have missed the point, that this is a "modified/improved" unit. According to the info on their website, they purchase the GM part new, and then do their "improvement" to correct the inherent design weakness of the factory original part. -I'm thinking that this would be a good reason for the price being a little higher?)
Hey, I can't speak for experience on this one, but I'm sure glad to be given hope that an "improved part" is available.
