Is he going to run leaves up front or coils? What off-set on wheels? Are they 15" wheels?
Do the axles have flatt top knuckles?
What D-44's is he using. We need more info...
Sorry here, bro'.
He said he has a HP44, so that means it's a Ford axle and does not have flat top knuckles. It makes little difference what wheel offset he's going to run, or whether he'll run leaves or coils. We don't need anymore information.
Hey, nice idea for a Xmas present for Dad.
The links that have been posted are good ones, should give you the info you need. I'll hit the high points. The Chevy D44 knuckles are flat on top because Chevy used a short curved steering arm that bolted to the top of the drivers side knuckle, hence the flat top that high steer arms are bolted to. The passenger knuckles are basically flat, but still need to be taken to a machine shop and milled perfectly flat and drilled and tapped for the studs. The Chevy came with a 6 on 5.5" bolt pattern on the hubs, so unless the rear axle is also going to be 6 on 5.5 (like Waggy stuff), you'll need F150 hubs and rotors to get 5 on 5.5" bolt pattern. It can be easiest, and many times cheapest, to just get new F150 hubs and rotors from a discount parts house, like Autozone. Anything from mid 70's to mid 80's works. Use the Chevy spindle and caliper, with the Ford hub and rotor. Now, since an XJ uses a 5 on 4.5" wheel bolt pattern, the rear axles will need to be changed to match the front 5 on 5.5" bolt pattern, but don't worry about that since your Dad has likely already considered it when he got the front D44. Then, you'll need to get the high steer arms, with studs, nuts and conical sleeves.
So, a parts list is:
Chevy D44 knuckles, calipers, and spindles
Ford F150 hubs and rotors
New high steer arms and hardware
Or, buy everything from Parts Mike.
If you can't find or afford everything, I'm sure he would appreciate whatever part of it you could get, I know I would.
