im stumped.. need suggestions

[jcblue]

i got my outter cab pieces, a and b pillars and all 4 cab supports replaced, i hung my doors and fenders back on the truck b4 i put my rockers and cab corners in. i can get my drivers door and fender lined up pretty good, but im having more trouble with the passenger side. I can make my body lines match on the p. side, but everything seems as if its too high, ie teh top of teh door rubs teh drip rail, and when i mock up the rocker, teh gap is 2x as wide as it should be, but i had to adjust the door that high to make the body lines in teh door match the cab corner. anyone got any suggestions..
my dad says, (and i trust his judgement, just seeing what everyone else says) that the cab may have saged at the window post and should try and push it out with a porta power. what do yall think?
thanks
