I SOAd my 74 with the old "saggy" stock springs and love it. In theory your plan will work. Your steering angles will come out correct but you will have the same problem I did. Your U-joints will bind. You will have to "clearance" the yokes to achieve angles past there design limits. It worked on mine but it is absolutely not the most desireable method. I am going to redo mine using the "cut and turn" method where the steering knuckles are cut loose and rewelded at the proper angle after the pinion is rolled up to match driveline angle.

Wardens used to do it right on the truck. They would drop one end of the spring, roll the axle out, reattach spring. With axle out of truck remove all brackets, perches, and mounts. U-bolt the axle loosely into the desired location aligning locator pins. Roll axle to aim at t-case output. You can even install driveshaft to check that pinion is exacly in line with shaft. During this stage you should put the weight of the rig back on the axles when checking to insure proper alignment of pinion and shaft. When you are sure you have it right, tack the perches in place, and measure angle of pinion drive flange. Remove axle, weld perches, cut knuckles loose, rotate ends to measured angle plus 3 or 4 degrees to get steering angles correct. Again, check your work by reinstalling axle in vehicle and check steering angle with weight on springs. If correct, remove axle and weld completely. Reinstall axle, install and weld shock mounts, brakeline brkts, etc. Thats the front. Rear is much easier.
