Rear-end conversion question
 

my recent 68 that i purchased has a 12 bolt rearend just like my 69 that i have. The 69 has been converted to 5 lug so i imagine someone just changed out the axles in it. Is that possible? Could i change the axles from a 10 bolt truck to a 12 bolt. Because the 10 bolt rearend comes from a 81-87 chevy and the u-bolt plates are on the wrong side and they dont have the hole for the bar therefore I just cant change out the rearends. I would think that if they are spline the same it should be a cake walk. Does anyone know the spline count for both before i start popping covers?

You could use that 5 lug rear end by utilizing one of these kits. I hear the axle swap wont work, there different lengths.

no way . the ten bolts you are refeering to are have 28 splined axles and the 12 bolt have 30

so the only way to make the conversion without changing rearends would be to find a rearend from a 72 truck with 5 lug. If thats the case, changing the whole rearend from a 72 would be just as easy.

You could do an axle/drum swap.
