I pulled the temp. sender from an original 1969 232, and it reads the same, and does not match 1970 specs either. The 1983, 70-something, and 1969 all read about the same. I tested cold and 165 degrees. The '69 sender read lower, but not much (notes are at home). The two newer senders were stamped with a different number than the 69 part, which got my hopes up. Does the right part actually exist?! _______________________________________________ AMC-List mailing list AMC-List@xxxxxxxxxxxx http://www.amc-list.com/mailman/listinfo/amc-list or go to http://www.amc-list.com
