Help with Axle Swapping

[mjgord51]

I have a 68 C10 w/ stock 12 bolt 6 lug rear end. I have read in another Forum that when using the frt spindles (5 lug) let say from a 1996 Tahoe 5 bolt lug truck that it would be the right move to also get the rear axles being it is also a 12 bolt rear end to end up with a complete 5 lug conversion setup onto my 68 C10.

PS, I have the spindles & calipers from that Tahoe on my truck w/ after market 6 lug x 1 1/4" rotors already and other than the 22" rims & tires it seams to do OK with what little I have drove it. *** ? will that axle swap work or not. Thanks in advance, mjgord51
