Temp and Gas gauge repair

I don't like to disrespect other peoples work. Lets call the following statements education.
The heatsink shown in those pictures is pretty much worthless in that configuration. The heat created by the regulater is directly behind the black area where its ID markings are. IF you were to open and examine any piece of electronics in you home you would find the entire flat backside of a regulater fastened to the flat side of the heatsink along with heatsink compound or silpad. No bent legs will be found either.
My younger brother has been with Bosch for 23 years. Head of field failure annalisis at their local antilock brake processor plant. He made sure my unit would not have field failures. A full year of redesigning and testing to satisfy both of us.
But hey if what you have there works and satisfies you... happy moparing :)
