For for all three kits around $140 inlcuding shipping. I didn't know the size of heater and adapter, so I order the governor case cover kits. I had no problems install block heater without governor case cover kit. So you might be able to save some money and time.
Excellent! Thanks for the write up and pictures. I would figure that any diesel sold, at least in the colder parts of the country, would come standard with the block heater.
