Too many frame questions! Need tons of advice!
 

OK, so I have my 72 Jimmy that is need of some TLC. The plan is to build a new frame from 2x4 .120" tubing. I need help and as much info, pics, you guys can give. I've built frames in the past but they were all going off of the original frame dimensions. I want this baby to lay body on bags with a Corvette C4 rearend. So what I need help with is the front end stuff. Do I need to make the frame hump up higher to achieve body drop? Or can I go off the stock dimensions with a drop member? Also, does anyone have any specs on building my own drop member? I can fab up almost anything and can't see laying down the cash on something I can build if I only new the dimensions. Thank you all!
