While it may work, my experience says It’s more likely that the car won’t sit the same on stands as it does on the tires. The dynamics of leverage at the front suspension may be working against you.

Set it on the ground, preferably at race weight with a but in the seat. Measure the current angle of the yoke on the rear end, and the output shaft of the transmission with a simple magnetic angle finder. Do the math to figure the angle like that. Then make the required adjustments at the perches and re-measure.

If you don’t have wheels & tires yet, I’d try to borrow some for a day, or just wait until you can do it correctly.

Only my 2c. Good luck.
