so i had a job today close to where the GMC i bought was so i thought i would check in and take a look for my self(if the brackets i was trying to get were going to mount to the cross member, if the shock mount were the same ,if the holes for a panhard bar were already in the frame)......then the guy that sold me the truck said he just bought another 70 chevy with a 71 clip .....i could go look at it and compare.....needless to say ....i swap for the chevy (cause i already have a new front bumper and good used front grill from my 72)so needless to say i now own a 70 chevy....with a replacement box .........pics to follow..........i hope tomorow
