I just do them myself , turn the front upper control are eccentric all the way out & the rear all the way inward , using a digital level or your smart phone adjust the upper control arm until you have 1/2 * of neg camber & set the toe in 1/16 using a tape measure
The hazard button was smaller in 70 , 71 -74 was fatter you can open the slot in the column or as I usually do file away at the rear of the button until it fits smoothly in the slot
