Looking for help. dana 35 to 8.25 with discs swap

Picked up a 8.25 rear end with xj disc breaks this weekend. (Thanks Bloodtype_jeep) Picked up the proper e-brake cables. (thanks Solomon7) I got my BDS lift on its way and im installing that on the 14 of this month with my pop(outdoors) and his partner. Im looking for someone or someones with garage space and the proper tools and the know how to help me get this upgrade done. We just moved into our new house and our garage is stacked so i cant just take it apart and take my time figuring it out in there. Any help would be appreciated. Jimmy:us:

I would do it at the same as your lift. That way you don't have to fuss with it twice when you replace the springs.
