i have a chance to pick up a set of axles out of a 69 bronco. my question is since the early D30 has drums is it possable to swap it to disks like you could with the D44? if so what all do i need?
 
Why would you want to do that? The Dana 30 is about as strong as the Dana 28.

If you are looking for strength, then go with the Dana 35, which is a bolt in swap, and do some of the mods to it listed in the Tech Library.

Yes, the EB dana 30 uses all the same swap parts as a EB d44. just find a pair of chevy d44 small bearing spindles, caliper brackets and calipers and a pair of ford 5 lug hubs.

But if it were me and I was swapping to a dana 30 I would use a jeep axle so my bolt patterns matched instead of using EB d30.

Thanks for the info. and the reason for not using a jeep D30 would be that i would be getting the D30 and the 9" that have matching gears already, and for about $40 more than i would pay for just the jeep axle from the JY.

i would want to do it for a few reasons.
1. i would get almost everything i need to swap it in for less than i would just buying the D35.
2. gears are matched to the 9" that comes with it so no need to regear the D35 or the 7.5.
3. if i come across a EB D44 it would be easy to slip right in. without changing anything.
