67 6 lug to 5 lug conversion.

[Dobster]

Is there a thread or link anyone can point me too?
Is there a direct axle swap off another chevy truck to convert the 67 6 lug to a 5 lug? I just got my posi unit installed, I assumed I could use the 70-72 5 lug axles but They are longer. I guess I should just pick up a complete axle from a 70-72 if I can find one. I could pick one up and transfer the posi. I already have a rear disk brake conversion set-up.

Early classics has a 5 lug axle swap for around 300 bucks. I'm assuming you have a 12 bolt 30 spline.

x2.... Especially if you already rebuilt the differential.
There aren't any direct swap axles. Go with aftermarket units which have zero wear & are stronger than OE.

just spent 500 on the diff wasnt wanting to spend another 300 on axles.
Thanks for the info!

If you just installed a posi, did you upgrade the bearings? seals?

I had my 71/72 rear rebuilt, I gutted it and cleaned it all up and still cost me $1000, that included the master rebuild kit and the ring/pinion to 3.73. no posi.

[Dobster]

I only changed the posi. The 373 ring and pinion was already installed about two years ago by the previous owner. I did use a gauge and tested the play. Right at .09. I used the original spacers. And checked the ware pattern. It was dead on with the previous diff. So I only paid for the Eaton series 4. I did all this thinking I could just swap the axels from a 71 or 72. So now I am going to buy a few axles in the near future. It just slows down my progress.
That's a sweet 65 in your sig. Clyde how's the gas milage?

Not to hyjack, but I'm in the same boat and curious about my options.

I have a 6 lug axle too, but it's garbage. Everything needs replacing. I can grab a local 12b/5 lug/ with 3.73s for around $180. Dunno the shape though. Was looking at putting a 9" together, but it's overkill and expensive. What do you guys think?

[ksbrktracer]

I wont say it is the best option ...... but it is a reasonable option. Having the axles and drums redrilled to 5 on 5 and the centers turned down to fit the 5-lug wheel cost me $85.00 locally , just need to make sure the axles arent wore out first . Now to me the best option for a fleetside truck is to go ahead and put the wider 71-72 rear axle in if possible. Opens up alot more options for wheels with the correct backspacing .

Re-drill them and press in 5 studs and get some 71/72 drums. Very common practice. Then get one of the many kits for the front offered for a disc conversion or a simple 5 lug conversion (CPP) being one of them if you want to go that route fro the front. We just did it on a 69.

If I could go back I would grab the 12 bolt for $180 and get it installed with 373's already installed the ring and pinion can stay saving a few hundred bucks.

Just remember the 70-72 rearends are 3/4" PER SIDE wider than the 67-69 rearends.

I would still buy new axles from Moser Engineering to replace those old axles.
$260 from Moser Engineering.

So you scored Axel's from a member on this board on a thread I started and you are just rubbing it in my face?

Haha Nope. Was thanking the guy I bought it from. Was from CList, not here. But it seems all my CList dealings so far (with this truck) have been with members I don't know! Kinda cool guys, the popularity and all. I don't run into people from my Blazer forum at all.

I'll thank all the replies myself, cause it helped me out of the same boat

Thanks for the input. Might be going this route if I can find a deal on a axle.
Thanks

Some people say to re-drill the studs is unsafe? Ive got time. I think I will ether buck-up and buy the axles or if I can find a good deal on a axle out of a 71-72 just re-build it with my diff. from my 67.
Thanks for the input. Good to know I have a few options here.
