Hey guys I'm putting my commander up for sale and removing the tranny gauge I found that I lost the original bolt that plugs the hole. Could you guys point me in the right direction on what the right size plug is and thread size? Went to the local dealership and they couldn't figure it out might as well be sitting on their hands all day. Thanks.
 
Yeah I'm not sure I assumed my exhaust manifold was that also but it was drilled by someone other than me and it isn't 1/8th npt. what does npt stand for? thanks for the post
 
NPT stands for national pipe thread. I think the drill bit i used for my egt probe was a letter R, and the tap size was a 1/8"-27 NPT tap.
