I need to know what size the bolts are for the transfer case/ 5 speed transmission fill/ check, and if they are the same size. They look like it. I don't have a socket or wrench big enough (biggest is 19 mm) . Thanks for the help.

 

They are the same size. I believe they are a 24mm Socket Head. Use a 6 point socket or they will strip real easy...

 

Yep. 24mm, or 15/16"(23.8125mm) works too

 

Cool. Thanks!
