for the differential cover? I need one...

 

Believe or not it is a 5/16-18 thread. So far it is the only inch series threads I have found on the truck.

 

Thanks

 

what is the stock length on those differential bolts ...?

 

By just eye balling them it looks to be around 1"..

 

You measure one up if you have them out ?

 

Sorry sonic they are all back in... Now that I look at a ruler they seemed to be between 1/2" and 3/4". Sorry

 

5/8" is the correct length for the stock diff cover. Need to go longer if adding a Pan-Hard bracket (7/8").

Fastener 101 tip of the day: The length on hex head bolts are measure from under the head. Counter sunk (flat head) screws and bolts are measured from end to end.

 

1/4 inch longer than stock and I'm using Hex Head stainless bolts ... So an inch from under the head should probably do it huh...?
