1972 Chevelle 10 bolt Question.

[RingMaster4x4]

How many splines are on the axle of a 72 chevelle 10 bolt?

 

[R72K5]

8.5" are 28 until 1988 or 89 then went to 30 spline

7.5" were 26 spline and went to 28 at same time

How can I tell if it is a 8.5" carrier?

The 8.5 will look just like a truck 10 bolt , with the little ears hanging off the bottom , and the cover even looks the same /forums/images/graemlins/thumb.gif

The cover looks the same but it does not have the wings.

Here is the only picture I have.

Simple fix, dump the 10 bolt and get a 12 bolt for it. /forums/images/graemlins/thinking.gif /forums/images/graemlins/whistling.gif

I believe that you have a GM 8.2 10 bolt . GM phased that rear axle out in the early seveties IIRC .

28 spleen!

You can hardly find a 12 bolt in Cali...If you do, your going to pay thru the nose for it. I ran a 10b 28 spline on my Elky for years with an eaton posi and lift bars. Never has a problem with it. cheapest swap would be a Ferd 9"

The only reason that I am looking for a 12 bolt is I have a 600HP 454 in mind for the chevelle. /forums/images/graemlins/screwy.gif /forums/images/graemlins/whistling.gif

You should forget the 12 and go with the 9" IMHO. My 67 Chevelle had a 575hp 396 and I went thru a couple 12 bolts before I dumped some cash on a 9" with 33 spline Moser axles and a Nodular 3rd member...no more breakage /forums/images/graemlins/waytogo.gif

I know as a "purist" that sounds evil! But I agree!! back when I was racing my 64 lemans, I went through 2 12 bolts before I spenta ton on another housing spent alot to get it strong enough to handle all the power I did have(484, proshot fogger) That I wished I had done a 9"!! would have been 1/2 the cost! It cost me 900 for my housing and have it narrowed! I could have bought a NEW 9" housing for 275.
