Thanks, Mike! I found a set on Ebay for a 55/56 and they told me it was the same as for my 58... What I found on Napa did not jive with that though! You have confirmed what I thought! Now to see if I can find some local somewhere cheaper than Napa! I'm going to call Brake and Clutch in Seattle tomorrow, I am having a hard time spending almost 45 each for the fronts from Napa!
