9 Inch question

[jamesrussell26]

Ok guys here's the deal. My 64 stepper has no original rear end.i do have a 9 inch from a 79 Ltd 2 . There is also sentimental reasons for using the 9, cost is not a real factor here.i have the tools and ability to shorten and do the welding properly. My question is does anyone know the lengths for the axle tube from pinion centerline to wms or backingplate? With pinion centered in frame? Done a lot of reading and searching on here but I have found just about every other measurement
