Ford 8 inch rearend swap

Just went out and did an actual measurement of the 8 inch Ford, and 7 1/4 "A" body rears. This is just a tape measure/"eyeball" measurement, so could be off slightly.
7 1/4: spring perch 43 1/4 inch. Axle flange 57 inch
8 inch: spring perch 43 1/4 inch. Axle flange 56 1/2 inch
Does not take into consideration brake drum thickness, as I don't have drums on the housings.
Just found this list of rear end dimensions.
