Help me choose a 351 Windsor

the cap I have wont fit a ford dist, I had an extra and just tried it on a duraspark, no go.....the only small cap/rotor to fit is the 1st gen duraspark or point type w female terms. You can get 8-9mm wires to fit them as well it will look even more stock that way, just paint the blue cap black, thats what I did.
 
After all these years, I've settled on a favorite spark plug wire set----Ford Racing's 9mm's. (they last, & you can't beat the price on em)They don't come with the female cap ends. Never liked the way those ends fit anyhow. I'll just stick with the big cap.
