Hello, I have an 84 244gl with a b23f. I just purchase an oil temp gauge and am in need of a sender. I talked to the guy at egauges and he said he can help me with the sender, but I need to know the thread size. My main question though, is that I have a oil pressure sender screwed into the hole by the oil filter, which feeds signal to my pressure gauge and idiot light. Where is a oil temp gauge connected? Someone mentioned to me something about a bolt in the head that when removed could be used to hook up a pressure gauge. Perhaps there? Any help would be greatly appreciated. Remulon
