Just a heads up, the 14 bolt conversion brackets do bolt right up to the Eaton as well, then all you need to do is get some front replacement disks for a 71 or 72 3/4T and longer studs, then use the stock Eaton rear hubs and your done. Be sure to get the 1 1/4 width rotors not the thin ones, then make sure when you buy the calipers they don't accidentally have the wrong width caliper in the correct box, it happened to me.

But you are correct about there being more available parts for the 14 bolt, all the bearings and seals are still available for the Eaton but the Pinion bearing is quite large and last i checked they said it was about $400 but don't quote me on that. Its the drums and brake parts and gears that are getting hard to get.

Yeah, I read that. And like you said, if I could get the 3.73 gears and pinion bearings, Id keep it. But looking at this as an ease to repair/fix down the road, I would rather have the ability to find the part easily.

So you kept your Eaton and did a disc brake swap?

Im also trying to lock down my engine/trans decision now to decide if having 3.73 gears over the 4.10 will make a difference. Going to make a post to the general forum for input. Hope to hear you chime in.
