Rear 4x4 leaf spring pack thickness??

So I'm hunting for a pair of unicorns, and would be greatful if any fellow F100 4x4 owners could confirm that the rear 9 leaf spring pack thickness is 3 inches. I'll probably have to have a set custom made, but I see there's a set available for 2 wheel drive but it has a spring pack thickness of 2 9/16" maybe I could recycle a few of my leafs to get the correct thickness. Thanks

Looking in the 1957-1963 Chassis Catalog the only half ton 9 leaf spring pack I find listed is B7C 5560-C measuring 2.59” thick. Maybe Bill will have a source that I don’t have, but it looks straight forward from the chart. Stu

Thank you, I have a hunch that is the 2 wheel drive part number. I'm open to suggestions BTW on alternative springs (3/4 ton) for my truck. If anyone has done business with a good Spring manufacturer feel free to share your experience.

It's both 2WD & 4WD! See post #5 for 1957/60 F100 2WD & 1959/60 F100 4WD rear spring applications.

Notice under F100 4WD that it shows B7C-5560-C being replaced by C5TZ-5560-D
