Tips re: relocating and welding motor mount perches?
So I'm making great headway with my 2.5L to 4.0L swap in my '95 YJ. I'm finally ready to set the new motor in the engine bay. As you may know, installing the 4.0 requires relocating the motor mount perches (moving them towards the front).
I have carefully and cleanly removed the existing perches, and prepped them up real nice so that they fit cleanly over the frame rail. All rust & paint has been removed, and I'm ready to weld with my MIG.
I have the engine hanging from an engine lift with a motor leveler, and have it as level as possible.
I plan to move the motor/trans/xfer case into position and align front/rear using the transmission mount (cross member) bolt holes. I also was planning to measure from the center of the crankshaft to each of the frame rails to center the motor left/right.
Any suggestions regarding how to make this easier and to get it right on the first attempt? Once the motor is nearly in position, do I just lower it until the perches sit firmly on the frame rails, and tack it into position?
I really only want to do this once and don't want to spend all weekend on it, so any tips are appreciated. Cheers.

UPDATE: 2.5L ENGINE RETIRED; she was still running strong at 212,000mi.
