It can DIY'd
I've Done it before, Just jack up the Vette in back, Pull the wheels, and then unbot the U-Straps from the Diferental, and unbolt the flanges from the Inbrd side of the spindles. The Inbrd U-jiont can be "Hamered" out just like any drive shaft. The Outbrds are tougher, as the flanges tend to bend. I ended up taking mine to a Machine shop for the outbrd sides.
