58" backing plate to backing plate should do it. I have to look around. Gearhead, I haven't been able to make it out to the yard you told me about yet, but hopefully soon. Oh, and I can't buy a parts car since I rent in the city and I barely have room for my car, much less another one, but that's a good suggestion.
