can anyone tell me what npt size the threads on the oil pressure sender are. also what size fitting is the petcock drain on the back of the block. also what is the easiest way to pass through the fire wall on the driver side . thanks for all the help.

i dont know, i dont know, and oh, theres one i can answer...there is a rubber grommet on the drivers side of the firewall. its not to hard to reach from under the hood and it leads to above the pedals on the inside..at least its there on my 98. just look in there, i just pulled mine out , cut the hole 'n put it back--easy cheese.
