6 lug to 5 lug options if you have both complete axles
My dilemma is this:
- I have a 6 lug 1968 12 bolt rear with 3.08 posi in good condition. - I have a 5 lug 1971 12 bolt rear with 3.73 open in good condition. (Axles are longer than the 1968 axles.) I need 5 lug 3.08 posi. I can put the 5 lug axles in the 1968 case but they sick out 1/4" more than the original 6 lug axles. I could pull the ring, pinion and carrier out of the 1968 case and put in the 1971 case and have what I need, but seems like a lot of trouble setting the gears up and all. I could have the 6 lug axles redrilled but the cost estimates are more than half of what it would cost to just buy conversion axles, which would be the easiest and most expensive solution. As far as I can tell there is no way to shorten the 1971 axles to the same length as the 1968 axles. Does anyone have any other ideas that I might be overlooking for a solution? |

Just put the 308 posi in the 5 lug rear its not as hard as you think read up how to do it .I did my first 12 bolt rear when i was 16 .Its a great way to learn .

Re: 6 lug to 5 lug options if you have both complete axles
If you decide to swap out the carriers number 1. The gear ratios are to far apart and you will not be able to swap ring gears on to the other carrier. 2 when you pull them apart make sure to keep track of the shims and what side they came out of. 3. It's a used rear gear set you will never get the mesh pattern as tight or even as a new gear set.
Read a couple of the posts on it and good luck |

What would it take to swap to disc on the rear and then I could use the 71 5 lug axles in the 68 case possibly? Anyone know if brackets are available for this?
