Axle Shafts
Ok so I was at a junk yard the other day and they had a pile of axle shafts from all these different Chevys. Would it be a good or bad idea if I just got those and put them in my rear end so I could get 5-lug? Right now I have a 70 6 lug 12 bolt. So what will I have to look for the figure out which ones will fit right?
I plan to jsut do the axles shafts and later get a 3:73 gear and posi put into my rear end have now.

Re: Axle Shafts
if you have a late 70, you can do this.
70 was a cross over year on the 12 bolt rear. The early ones were narrower than the later ones. If you have the later one, you can use any axle out of a 5 lug 12 bolt truck rear. |

Re: Axle Shafts
So where can I measure to see which I have? My truck was first registered on 11/69 if that says anything.

Re: Axle Shafts
If you measure between the backing plates on the rear end, the narrow one will be 56" and the wider one will be 57 1/2". If your rear end measures 57 1/2" between the backing plates then the 71 (5) lug axles will work.
Although you can stick the 71 axle in a narrow 70 rear end the 3/4" length difference lets the axle bearing ride on the edge of the ground surface. (The axle shaft acts as the inner race for the axle bearing). If you have the narrow rear end, redrilling your existing axles forthe 5 lug pattern is still an option. Jim |

Re: Axle Shafts
Another route on the narrow axles, is to go aftermarket. I have Moser axles in my 69, & atho a little more expensive, they are new/straight/non worn pcs

Re: Axle Shafts
About how much would redrilling cost at a machine shop?

Re: Axle Shafts
In addition to the redrill you would have to turn down the center protrusion that fits in the center hole of the rear drum a bit. I did this years ago, but can't remember much about it... I used new 5 bolt drums and they wouldn't fit because of the center hole.

Re: Axle Shafts
Ok so I measured it and I got the wider axle, so what year trucks can I get the shafts from?

Re: Axle Shafts
71-72 fer sure, not so sure about the 73-84... although I think I saw a thread once saying they would fit also. I'll see if I can dig it up.
Good luck, Rg

Re: Axle Shafts
71-82? (82 I think was the end of the 12 bolts), should all swap. to be sure, you can measure from the flange to the "button" end . I had the measurements when I ordered my axles.....but its been a while, & the old memory "aint as good as it once was"

Re: Axle Shafts
Am I remembering wrong...or the axles out of the 10 bolt will fit in there too. (the 7? to 87)
However, somewhere in there they went to metric studs which would be a hidden cost... |
