I need to replace 3 freeze plugs on the block right below the exhaust manifold, I measured 2.390 inches. But every time I go to a parts store the biggest they got is 1.5 inches. any body know where I can get 3 of these with out buyin a freeze plug block kit????

 

Napa, or from Cummins. Dodge has them also....I'd get the block kit, that way, whenever you pull the motor, that'll be 3 less you'll have to worry about changing. If your motor is out of the truck, replace all of them....

 

motor was all still in truck and running... just had them leaking... napa couldnt find them.... but I found some. thanks
