They almost exclusively only sell to the gov't now and not too many civy trucks use an air activated actuator. The part number is EV CA0180. 180 being the tem. at which it opens. Price is $143.92 The big dealers don't have them unless they lied to me. The aluminum back is not exactly the same as the original, however, it does the same job.
