rear diff compatibility

Matt13 · September 19, 2024, 08:39:08 PM

I have a 1973 Barracuda with a 727, currently a 741 case rear diff. I've located a rebuilt 489 case rear diff with 3.55 gears and sure grip. Owner says it was out of a 1970 Charger. My question is will my axles fit without issue, and what will I need to change on my yoke.
TIA

It's a bolt in as far as axles go if still running the OEM style axle bearings.

The yoke, if the driveshaft is different from the yoke, get a 7260 x 7290 conversion U-joint
