Call MH directly. If Year None doesn't sell/list it. MH can sell to you directly. Call them.
I think I am ok; just a little work to do. I have what I think are correct connectors coming and will have to move the wires. Hopefully that goes smoothly. And I did the whole marking wires deal though I must have missed a few. Luckily, there are not too many places to go in 1965. Lol
I looked at M & H catalog on their website. They don’t show much for 1965 and it says they don’t make dash harnesses. ???
