Re: '67 disc brakes for a 4x4??
The front axle is the old closed knuckle design, and you can convert them to disc. I know Blackbirds sells a kit, but most of the time I see people just swap out the Dana 44 for a later model one with disc/open knuck.

The on;y drum brake Dana44 I know of that can easily be converted to disc is the open knuckle '70.

Mmm
Theres a junked 72 4x4 cheyenne at the junkyard. It makes me wanna 4x4, too bad your not closer you could steal the frontend out of it. Btw, whats a ballpark price of a 4x4 lwb 72 frame with a 4" block lift? No transfer or motor/driveshafts. |

Yes, much better turning radius and parts availability...that along with the advantage of disc brakes and its one of the easiest and best upgrades you can do.

Check the dif cover bolts, and look for a tag.
Here is mine, and the tag will give info on the gear ratio. |
Re: '67 disc brakes for a 4x4??
no tag. but i did come across an open knuckle dana 44 around me for 100 bucks. the only thing is wrong gearing. anyone know if i could drop them in from my current axle to a new axle??
|
Re: '67 disc brakes for a 4x4??
You might be able to but I can't remember for sure. Just make sure you don't end up getting a 10 bolt. Stay with a D44, 70-78 I believe.

Re: '67 disc brakes for a 4x4??
can anyone help me??? i've been told the ring and pinion are a definate, but i may need a new carrier, depending on if the axle shafts are 30 spline or the other one(more splines on that one if i remember right). this sound right??
|
Re: '67 disc brakes for a 4x4??
I am no expert on axles, but there are differences on the axle diameter and spline count on various years/models of trucks that they came out of.
If I was in your shoes, and I had a line on a complete D44 for a hundred bones I'd snag it. Then take it to a expert and have it gone through. Ask the expert about your current axle, and inquire about re using the ring and pinion. They should tell you whether or not if it is interchangeable, and check to see of the 40 year old parts are still good. If it were me, I'd spring for a complete overhaul with new matching gear ratio ring and pinion. I'd also price out a new locker, just in case they had a deal to offer me or if I could afford a new one in the first place. |
Re: '67 disc brakes for a 4x4??
Your ring and pinion should be fine to use on the newer diff. The older diffs might have had a coarse spline pinion, and might have had coarse spline side gears. What gear ratio do you have now, and what gear ratio is the newer diff?

Re: '67 disc brakes for a 4x4??
The carrier split on the old stuff is 3.73. So if you have 3.73 now, and purchase a diff with 3.08/3.23/3.54, your gears will swap to the other carrier no problem. If you have 4.10 now, you will have to reuse your carrier to do the swap. You might be able to just swap the side gears if you have coarse side gears, and want to swap to fine-spline side gears.
Follow me? If you have a coarse spline, 4 series, but wish to swap to a '72 up diff, you would have to use your carrier, the other carriers side gears, and your old diffs gears, to whack into the newer diff. Otherwise, if you're playing with all 3 series stuff, it's much simpler. Cheers. |

Re: '67 disc brakes for a 4x4??
and you can do the same thing by turning on the front too???
