Interested in the rear ring and pinion if the ratio is 410.

Thanks for the intrest. BUT.
I apologize that i am not very knowledgeable about the different 4 wheel drive components. Especially after 1972
I have been told by a few forum member that the 4 wheel drive train is from 1973-1978 as it has a Dana 60 in the rear and has the yellow spicer hub dials.
The frame is a 1972 frame.
After I get the junk body off, I will repost with pictures.
If can't sell the frame and drive Train Together, I will the part it out.
Thanks everone.

dana 60 could be correct for 72, 73 on up used 14 bolt corporate in 3/4 ton and the big hubs with yellow centers bolt up the same as the blue centers or someone might have changed the whole front differential since the spring spacing is the same up to 88 on trucks and 91 on blazers and suburban's. not sure of the exact year GM stopped using the big hub fronts.

Thank you Jerry for posting your knowledge of 4 weel drives. Did the 72s have a large ( about 4-1/2 inch) one piece drive shaft ? It is a long bed, Dana 60 in the rear and Dana 44 up front, if i remember correctly.
