congratulations on the completion!
I'm starting my process now.
parts list :
early 98 (p-pump 12v) 2500(8800lbs)
01 2500 front axle 3.55 complete all members attached, cut from donor end by seller all bolts left installed . arms Sawzall, shocks shaft torched , ect.

my question is what do I need to buy to install?
TRE for box went with pitman arm (torched sleeve) .
taper is diffrent on 01 nuckles, from my new(15k mi on compleet stearing rebuild) 98 hd t style?
Do i have to go with 01's crap y style? then cobble a workaround to attach to the 98's red head box with brace?
will the refrenced 08+ t style work on my 98/01 setup?

purpose:
bought truck with bad pinion berrings(started skipping teath on 2nd use) $250 for complete 01 Vs 1.5-2k for 3.55's install +- housing damages.
big brakes. 2 piston calipers , drop off rotors, option for factory bigger rotors ,
CAD no change currently kit +free-spin hubs planned.

dream big; chisel down to reality
a proper highjack is the only way to cut the troll's off at the knees and get responses from knowledgeable folks. TIA for your understanding of this.
