Odd dimensions on a body 8 3/4

Last time I installed a shorter differential I bent my own lines and flared them.

if you don’t want to bend and flare your own the if you can find sections of line with pre installed fittings at the auto parts store that are a little long you can put a few slight bends in the length so they fit.

The lines with some copper in them are much easier to bend with a hand held bender than steel lines.
