Question About Axles - The 1947 - Present Chevrolet & GMC Truck Message Board Network

ChrisCostlow · 01-10-2018, 12:45 PM

Good Morning Everyone

I'm buying a rebuilt axle for my 72 Blazer CST. Does anyone know the measurement center to center on the leaf springs? And what's the difference between a 10 bolt corporate axle and the Dana 44 for the front?

Appreciate the help.

I take it you dont have the original axle?

10 bolt and a D44 are basically the same but the 10 bolts are from later model trucks. Not sure they perches will line up for you.

Any D44 from a 69-72 K5/K10 will work for you, I'm pretty sure.
