No body drop, z'd and notched only. You can unbolt the crossmember with all the suspension attached from a squarebody, do the same to your 64, roll the old one out and roll the new one under it and it will bolt right up to the stock frame with the exception of one hole on either side. You can swap it all out in a day easy. Only issues would be steering linkages(tie rods, drag link, etc...) size differences but you just gotta see what you got. Company's like CPP sells tie rod sleeves to match it all up. I did raise the tranny member the same as the z but I don't think you have to. I raised the whole drivetrain 3 inches but that was personal choice.
