New Dana 60 Help please

This other guy said his rear had 30 splines too

Which Junkyard Vehicle for a Dana 60 Drag Car
30 spline axles are what also came out of my 60HD.

you can build that rear for your car If you want. It’s heavier than a standard Dana60 with the extra webbing and thicker axle tubes. It takes all the same parts.

But like stated earlier, you’re gonna have to cut it down and weld on car ends, and relocate the perches.
