The threads on my oil pan drain plug are a little bit messed up, threads in the pan are fine it's just the plug. What size is it and what pitch is the thread? I'm going to replace it with a magnetic drain plug but I need to know what size it is.

Thanks for any input.

 

Autozone's site shows a 302 having a 1/2-20 drain plug. Go there and plug in your truck with the 351w and see what it says.

 

My 351W takes the same size plug, thanks for the info!
