With the 351W being so much wider I did not want to reuse these. I used FMS 8mm wires with them and they fit perfect. If you want to use a larger diameter plug wire the black guides can simply be drilled out to fit them. They are in great shape as you can see from the pictures and the price is $30 plus shipping.
