Hi EZchevy truck guy here. You must change the whole cross member. the 62 dose not have a place for the spring.There are 7 bolts on each of the frame. four bolts on each side line up. the other three need to dill out. I have 2 62s a 61, That I have changed. I Used a 68 on one 74 on one,65 on one. I changed over due to cost of ball joints. The 62s are $140.00 each. And the others are $30.00 each. Hope this helps.
