ford gpa g504

I brought my leaf springs in for a rebuild and I was asked what the arch should be. Normally the rebuilder just looks it up in his reference book but he has no listing for GPA's.
I see this question was posted by Tony on G503 in 2005 but it doesn't appear the answer was ever posted.
I PM'd Tony who said said to contact Richard who said to contact John Hecker on G504. I can't find John Hecker in the membership list. Does anyone have the arch figures? Thanks David

Does any one have the spring arch measurments??
Thanks David

David, the numbers are now there in the same G503 post I referred to. Scroll down about half way.
