axle swap question?
 

Will the rear axles out of my 70 1/2t 6lug 12bolt swap out with a 12 bolt 5lug axles? I'm sure there is more to it then just swapping them but just wondering if they would likely interchange for a easy 5 lug conversion.

Anyone? i've wanted to swap too mainly for a different gear ratio. Sorry not trying to thread steal on ya

70 could have had either the narrow 67-69 rear or wider 71-72 style. As long as you have the wider rear, the 5 lug axles should be a direct swap.

Thats what I was afraid of. I was wondering if there might be a diff axle length. Jsmith, I know that changing axle aren't going to give you a different ratio. Changing ring and pinion is going to give you diff ratio's.

Just measure and you will know, our 70 has the wider one, yours may too.

most 1970 trucks have the wide rear.

thats backing plate to backing plate for measurement right?
