Hello, I got a 1950 3100. I'm installing an open driveshaft axle. I bought the offset spring perches with the extra hole to center the axle. Ok, so now I got them. I didn't buy that big kit with the tie plates and the u bolts. Decided to just drill my own and buy the u bolts separate. Question. My center bolt is supposed to go in the 6th hole right? Not the very center one? I'm making mine to match these in the picture.
