bolt size/thread count??

i am looking to see if any one knows the size of the threaded holes x2 on the drivers side fender right next to the fuse box in the engine bay. working on my dual battery set up and going to mount the dc-dc charger there. any info on this would be helpful. thanks...........

 

Take a bolt off of something else on your truck. Try to fit it in the hole. Take one that fits to the hardware store. Find a match. Buy it. Put it on. Done.

M6 is my bet. Could be M8.

 

m8 x 1.25 on drivers side
m6 x 1 on passenger

i used thread testers to confirm on a previous post
