Dana 30 knuckle questions

[schardein]

I am working towards converting my 1991 2wd MJ to 4wd.

 

I have a factory D44 rear, 4wd AW4 trans, 231 and 242 cases (plan to use the 242), and a 1985 XJ Dana 30.  Plan is to have 3.73 gears and 30" or 31" tires.

 

The Dana 30 is high pinion, non disconnect, factory 3.73 gears.  I have XJ 1996 shafts and unit bearings to go in it.

 

My question is the knuckles.  They are two piece, see picture.  Initially, my plan was to use "1991" parts so that down the road, when it came to to replace rotors or brake pads, I could use "stock" parts.  I do have a 1993 XJ D30 I could rob the knuckles off of.

 

Either way, the axle will get new ball joints, rotors, calipers, and pads.  

 

Are there pros/cons to retaining the early knuckle with bolt on caliper mounts, other than it won't use "factory 1991" parts?

I merely pointed in a direction. 

 

There are several 'big brake' directions you can take....ie....Cobra Marty. 

 

If you ever want the option........those are the only knuckles which give you options, aside from the Vanco knuckle or going the WJ route which is another direction altogether. 

 

Since you don't want options........those knuckles are worth good money, not here, elsewhere.

Now that's good info, thanks.  That knuckle in the eBay listing doesn't even have the bolt on caliper mount.

I would take the knuckles off the 1993 XJ.  One less part for rust to slowly wear down and loosen up on the front end.
