47-55.1 Jaguar Xj6 front subframe swap on 52' 3100 help

another good thing to do before removing the donor's suspension is to place the donor car on a flat level surface, air up all the tires to factory spec and ensure they are the correct sizes, remove stuff in the trunk or interior that wasn't there when the car was new, then take an angle measurement on the lower control arm, fore to aft, so you know what angle it is supposed to be at when installed in your truck. duplicate that angle with your truck at the rake angle you want and the tire diameters you want. I use a digital torpedo level for this, they are fairly cheap, as far as tools and truck parts go, and you will likely need one when doing the suspension install anyway. they can be placed on a 4ft level (which is used as the straight edge to support the short level) to set your truck frame up level side to side and at the rake angle you desire.
