Ford 8 inch rearend swap

I built and installed a ford 8” into a 68 dart a couple years back for a friends sons car. The total cost with brand new gears, limited slip center section, axles and 10” brakes from a ford aerostar van was $900. We couldn’t find a 8.75 for less than $800 local and that’s not even rebuilt.

From my memory the spring perches on the axle we used were about 1/8” inboard, it pretty much bolted right in and I had to use a conversion ujoint but no changes to the driveshaft had to be made.
